III-B3 Ordering Information   INTRODUCTION The term "microcomputer" has been used to describe virtually every type of small computing device designed within the last few years. This term has been applied to everything from simple "microprogrammed" controllers constructed out of TTL MSI up to low end minicomputers with' a portion of the CPU constructed out of TTL LSI "bit slices." However, the major impact of the LSI technology within the last few years has been with MOS LSI. With this technology, it is possible to fabricate complete and very powerful computer systems with only a few MOS LSI components. The Mostek Z80 family of components is a significant advancement in the state-of-art of microcomputers. These components can be configured with any type of standard semiconductor memory to generate computer systems with an extremely wide range of capabilities. For example, as few as two LSI circuits and three standard TTL MSI packages can be combined to form a simple controller. With additional memory and I/O devices a computer can be constructed with capabilities that only a minicomputer could previously deliver. This wide range of computational power allows standard modules to be constructed by a user that can satisfy the requirements of an extremely wide range of applications. The major reason for MOS LSI domination of the microcomputer market is the low cost of these few LSI components. For example, MOS LSI microcomputers have already replaced TIL logic in such applications as terminal controllers, peripheral device controllers, traffic signal controllers, point of sale terminals, intelligent terminals and test systems. In fact the MOS LSI microcomputer is finding its way into almost every product that now uses electronics and it is even replacing many mechanical systems such as weight scales and automobile controls. The MOS LSI microcomputer market is already well established and new products using them are being developed at an extraordinary rate. The Mostek Z80 component set has been designed to fit into this market through the following factors: 1. The Z80 is fully software compatible with the popular A CPU offered from several sources. Existing designs can be easily converted to include the Z80 as a superior alternative. 2. The Z80 component set is superior in both software and hardware capabilities to any other 8-bit microcomputer system on the market. These capabilities provide the user with significantly lower hardware and software development costs while also allowing him to offer additional features in his system. 3. A complete development and OEM system product line including full software support is available to enable the user to easily develop new products. Microcomputer systems are extremely simple to construct using Z80 components. Any such system consists of three parts: 1. CPU (Central Processing Un it) 2. Memory 3. Interface circuits to peripheral devices The CPU is the heart of the system. Its function is to obtain instructions from the memory and perform the desired operations. The memory is used to contain instructions and in most cases data that is to be processed. For example, a typical instruction sequence may be to read data from a specific peripheral device, store it in a location in memory, check the parity and write it out to another peripheral device. Note that the Mostek component set includes the CPU and various general purpose I/O device controllers, as well as a wide range of memory devices. Thus, all required components can be connected together in a very simple manner with virtually no other external logic. The user's effort then becomes primarily one of software development. That is, the user can concentrate on describing his problem and translating it into a series of instructions that can be loaded into the microcomputer memory. Mostek is dedicated to making this step of software generation as simple as possible. A good example of this is our assembly language in which a simple mnemonic is used to represent every instruction that the CPU can perform. This language is self documenting in such a way that from the mnemonic the user can understand exactly what the instruction is doing without constantly checking back to a complex cross listing.  Z80'CPU ARCHITECHURE A block diagram of the internal architecture of the ZSO-CPU is shown in Figure The diagram shows all of the major elements in the CPU and it should be referred to throughout the following description.

The STD-Z80 BUS uses a motherboard interconnect system concept and is designed to handle any MD Series Card type in any slot. The modules for the STD-Z80 BUS are a compact x inches which provide for system partitioning by function (RAM, EPROM, I/O). This smaller module size makes system packaging easier while increasing MOS~LSI densities provide high functionality per module. addition, an MK Counter Timer Circuit is included on the MDX-CPU1 to provide counting and timing functions for the Z Either EPROM can be located at any 2K boundary within any given 16K block in the Z80 memory map via a jumper arrangement. The MDX-CPU1 can be used in conjunction with the MDX-DEBUG and MDX-DRAM modules to utilize DDT and ASMB in system development. This is accomplished by strapping the scratch pad RAM to reside at location F FOO so that it will act as the Operating System RAM for DDT The MDX-CPU1 is also available in 4MHz version (MD~-CPU). In this version, one wait cycle is automatically inserted each time on-board memory is accessed by a read or write cycle. This is necessary to make the access times of the PROMs and the scratch pad RAM compatible with the MK MHz ZCPU. ELECTRICAL SPECIFICATIONS WORD SIZE Instruction: Data: 8, 16,24, or 32 bits 8 bits CYCLE TIME The MD Series of OEM microcomputer boards and the STD-Z80 BUS offer the most cost effective system configuration available to the OEM system designer. Clock period or T state = microsecond @ MHz or = microsecond @ MHz Instructions require from 4 to 23 T states MDX-CPU1 DESCRIPTION MEMORY ADDRESSING The MOSTEK MDX-CPU1 is the heart of an MD Series Z80 system. Based on the powerful Z80 manicapital.comcessor, the MDX-CPU1 can be used with great versatility in an OEM microcomputer system application. This is done simply by inserting custom ROM or EPROM memories into the sockets provided on the board and configuring them virtually anywhere within the Z80 memory map.

The STD-Z80 BUS uses a motherboard interconnect system concept and is designed to handle any MD Series card type in any slot. The modules for the STD-Z80 BUS are a compact x inches which provides for system partitioning by function (RAM, EPROM, I/O).

The MD Series of OEM microcomputer boards and the STD-Z80 BUS offer the most cost effective system configuration available to the OEM system designer. MDX-PIO DESCRIPTION The para"el I/O controller (MDX-PIO) is a highly versatile unit designed to provide a variety of methods for inputting and outputting data from the MD Series microcomputer system. The system is designed around two Mostek MK ZP10 para"el I/O controllers which give four independent 8-bit I/O ports with two handshake (data transfer) control lines per port. The ZPI0's are designated PIOl and P Each has an I/O port pair designated A and B. Each port pair of each PIO have similar output circuitry. A" I/O lines are buffered and have provisions for termination resistors on board. A" port lines are brought to two 26 pin connectors; two ports per connector. Figure 1 illustrates in block diagram from the major functional elements of port pair A and B of PIO 1. These elements can be defined as the resistor termination networks, data buffers, port configuration control, MK PIO, and address decode and data bus buffers. Input and output from the ports are provided through J1, a 26 pin connector. This connector provides data paths for the two ports and their respective handshake signals. One pin socket is provided per port for resistor dual inline packages so that terminations may be placed on the data lines. A para"el termination is provided for each 8-bit port data line plus the input strobe (STB) handshake line. The MDX-PIO is normarry shipped with 1K pu"up terminators. In addition to the para"el termination resistors, the ready (RDY) handshake output line is series terminated with a 47 .n resistor. This is used to damp and reduce reflections on this output line. Port A and B data bus lines are buffered using quadruple non-inverting transceivors. The buffers can be configured using port configuration jumpers to provide fixed Input, fixed Output or Bidirectional (Port A only) signals. Further the transceivers are configured such that port direction can be selected in 4-bit sections. The transceivers are mounted in sockets so that they can be easily replaced with their complements in order to achieve a polarity change if desired. The handshake lines are also fully buffered. The port configuration control provides jumper options to independently control the polarity or "sense" of each handshake line so as to further ease the interfacing between the MDX-PIO and peripheral devices. The MK, PIO para"el I/O controller is the heart of the module. This circuit is a fully programmable two port device which provides a wide range of configuration options. Anyone of four distinct modes of operation can be selected for a port. They are byte output, byte input, byte bidirectional (Port A only) and bit control mode. The PIO also automatically generates a" handshaking signals in a" the above modes. 15 MDX-PIO BOARD 16 47n MDX-PIO BLOCK DIAGRAM FOR PI01 (PI02 IS IDENTICAL) ROY DATA BUFFER 1 (4) PORT A (4) UJ i5 o ADDRESS DECODE MK3B81 CXl AND 6 DATA BUS N I- UJ PIO I BUFFERS CONTROL(9) (4) PORT B (4) ROY The Pia permits total interrupt control so that full usage of the MDX-CPU 1 interrupt capabilities can be utilized durinq I/O transfers. Also the Pia can be programmed to interrupt the CPU on the occurrence of a specified status condition in a specific periph-eral device. The Pia circuit will provide vectored interrupts and maintain the daisy chain priority interrupt logic compatible with the STD BUS. The address decoding, interface and bus management for the board are performed by the address decode and data bus circuit. Each MDX-PIO port has two addresses, one for Control and one for Data. A total of eight addresses are utilized per board. These addresses are defined in the table below. The circuitry for the other two ports provided by Pia #2 is identical to Pia #1. The port configuration logic, buffers, termination and pin out on connector J-2 is duplicated for Pia #2. These two ports share the address decode and data bus buffer circuitry with Pia #1. The only differences are in the address decoding as given in the port address table, and Pia #2 is lower priority in the daisy chain interrupt structure.

The STD-Z80 BUS uses a motherboard interconnect system concept and is designed to handie any MD Series card type in any slot. The modules for the STD-Z80 BUS are a compact x inches which provides for system partitioning by function (RAM, EPROM, I/O). This smaller module size makes system packaging easier while increasing MOS- LSI densities providing high functional ity per modu Ie. The MD Series of OEM microcomputer boards and the STD-Z80 BUS offer the most cost effective system configuration available to the OEM system designer. MDX-SIO DESCRIPTION The Serial Input/Output Module, MDX-SIO, is designed to be a multiprotocol asynchronous or synchronous I/O module for the STD-Z80 Bus. The module is designed around the Mostek MK Z80SIO which provides two full duplex, serial data channels. Each channel has an independent programmable baud rate clock generator to increase module flexibility. The MOX-SIO is capable of handling asynchronous, synchronous, and synchronous bit oriented protocols such as IBM BiSync, IBM SDLC, HDLC and virtually any other serial protocol. It can generate CRC codes in any synchronous mode and can be programmed by the CPU for any traditional asynchronous format. The serial input and output data are fully buffered and are provided at the connector as either a 20m A current loop or RSC levels. A modem control section is also provided for handshaking and status. The MDX-SIO module can be jumper configured as a data terminal (DTE) orasa modem (DCE) in order to facilitate a variety of interface configurations. Figure 1 is a block diagram of the MDX-SIO module. It consists of five main elements. They are the channel configuration headers, line drivers and receivers, MK ZSI0, programmable Baud rate generators, and address decode and data bus buffers. Input and output to the board is provided via two 26 pin connectors. One connector is dedicated for each channel. Several features are available as options that are selected via the channel configuration header. The headers are used to select the orientation of the data communication interface and the mode of the 20m A current loop. The MDX-SIO can be selected to act as either a terminal or processor (Data Terminal Equipment DTE) or as the modem (Data Communications Equipment - DCE). The header allows reconfiguration of both data interchange and modem control signals. This allows increased flexibility necessary to link different hardware elements in OEM data link systems and networks. The module is shipped from the factory wired as a DTE interface. The MDX-SIO has different selectable options for the 20mA current loop. The receiver and transmitter functions can be reconfigured on the module to allow for reorientation of these signals. Also the receive and transmit circuits can be selected to function in either an active or passive mode. In the active mode, the MDX-SIO module provides the 20mA current source. In the passive mode, the module requires that the loop current be provided. The latter is the same mode as that of a Teletype. 21 MDX-SIO BOARD 22 MDX-SIO BLOCK DIAGRAM FIGURE 1 CHANNEL A RS DATA AND MODEM CONTROL 20 MA SERIAL INPUT/OUTPUT ADDRESS STD-Z80 BUS DECODE AND CHANNEL B DATA BUS BUFFERS 20 MA SERIAL INPUT /OUTPUT RS DATA AND An E IA and 20mA current loop interface circuit is used to provide the necessary level shifting and signal conditioning between the MK ZS10 and the connector. These line drivers and receivers provide the correct electrical signal levels, slew rate and impedance for interfacing RSC and 20mA current loop peripherals. Additionally, optical isolation is provided for both transmit and receive circuits in the 20mA current loop mode. The Mostek MK ZS10 is the central element of this module. This device is a multifunction component designed to satisfy a wide variety of serial data communications requirements in microcomputer systems. Its basic role is that of a serial to parallel, parallel to serial converter/controller but within that role it is configured by software programming so that its function can be optimized for a given serial data communications application. The MK provides two independent full duplex channels; A and B. • • Asynchronous operation (Channel A and B) - 5, 6, 7, or 8 bits/character - 1, 1 Y, or 2 stop bits - Even, odd or no parity - x1, x16, x32 and x64 clock modes - Break generation and detection - Parity, Overrun and Framing error detection Binary Synchronous operation (Channel A only) - One or two Sync characters in separate registers - Automatic Sync character insertion - CRC generation and checking • HDLC or IBM SDLC operation (Channel A only) - Automatic Zero insertion and deletion - Automatic Flag Insertion - Address field recognition - I-Field residue handling - Valid receive messages protected from overrun - CRC generation and checking The MK also provides modem control inputs and outputs as well as daisy chain priority interrupt logic. Eight different interrupt vectors are generated by the SID in response to various conditions affecting the data communications channel transmission and reception. Address decoding, STD-Z80 BUS interface and bus management for the module are performed by the Address Decode and Data Bus circuit. The MDX-SIO contains command registers that are programmed to select the desired operational mode. The addressing scheme is as follows: XXXXX 00 XXXXX 01 Channel A Data' Channel A Control Status XXXXX 10 XXXXX 11 Channel B Data Channel B Control Status The X indicates the binary code necessary to represent which of the 64 port addresses is selected by on board strapping. Each channel has an individual programmable' Baud rate generator. The X 1 multiplier on the ZS10 23 must be used in the synchronous mode. The X16, X32, or X64 ZS10 clock rate can be specified for the asynchronous mode. Table 1 indicates the possible Baud rates available for both operation modes with the ZS10 Data Rate multipliers.

MD SERIES MICROCOMPUTER MODULES Z80 Microcomputer Debug Module (MDX-DEBUG) HARDWARE FEATURES MD SERIES GENERAL DESCRIPTION o o o o The MD Series and the STD-Z80 BUS were designed to satisfy the need for low cost OEM microcomputer modules. The STD-Z80 BUS uses a motherboard interconnect system concept and is designed to handle any MD Series card type in any slot. The modules for the STD-Z80 BUS are a compact x inches which provides for system partitioning by function (RAM, EPROM, I/O). This smaller module size makes system packaging easier while increasing MOS-LSI densities provide high functionality per module. HARDWARE DESCRIPTION The MDX-DEBUG module has sockets for 10K bytes of masked ROM that are filled with a Z80 firmware package (DDT/ASMB). This module has a STDZ80 BUS interface and is available in both MHz and MHz versions. Included on-board is a fully buffered asynchronous I/O port capable of Baud rates. Serial data interfaces are available for 20mA current loop (with reader step control) and RS The on-board Baud Rate Generator is selectable to all common Baud rates from to 19, Baud. FIRMWARE DESCRIPTION DEBUGGER DESCRIPTION DDT is the Operating System for the MDXDEBUG Module. It resides in a 2K ROM (MK series) resident on the MDX-DEBUG Module. It provides the necessary tools and techniques to operate the system, i.e., to efficiently and conveniently perform the tasks necessary to develop microcomputer software. DDT is designed to support the user from initial design through production testing. It allows the user to display and update memory, registers, and ports, load and dump object files, set breakpoints, copy blocks of memory, and execute programs. 27 MDX-DEBUG BLOCK DIAGRAM ADDRESS J \/ \=) BUS INTERFACE MEMORY ~ELECTION LOGIC LOGIC AND CONTROL -.

Display and/or update the content of Ps I/O port s. D s, f Dump the contents of memory locations s through f in a format suitable to be read by the L command. Load, into memory, data which is in L the appropriate format. Es Transfer control from DDT to a user's program starting at location s. H Perform 16 bit hexadecimal addition and/or subtraction. C s, f, d Copy the contents of memory locations s through f to another location in memo ory starting at location d. Insert a breakpoint in the user's proBs gram (must be in RAM) at location s which transfers control back to DDT This allows the user to intercept his program at a specific point (location s) and examine memory and CPU registers to determine if this program is working correctly. R Display the contents of the user registers. The s, f, and d represent start, finish, and destination operands required for each command. MEMORY, PORT AND REGISTER COMMANDS (M, P, R) Ms 28 The M, P, and R commands provide the means for displaying the contents of specified memory locations, port addresses, or CPU registers. The M and P commands sequentially access memory locations or ports and display their contents. The user has the option of updating the content of the memory location or port. (Note some ports are output only and their contents cannot be displayed). The M command also gives the user access to the CPU registers through an area in RAM called the Register Map (discussed in the Execute, Breakpoint section below). The M and R commands are used to tabulate blocks of memory locations (M) or the CPU registers (R). The M command will accept two operands, the starting and ending address of the memory block to be tabulated. The R command will accept either no operand or one. If no operand is specified, the CPU registers will be displayed without a heading. If an operand is specified then a heading which labels the registers contents will be displayed as well. EXECUTE AND BREAKPOINT (E, B) The E command is used to execute all programs, including aids such as the Assembler. The B command is used to set a breakpoint to exit from a program at some predetermined location for debugging purposes. At the instant of a breakpoint exit, the contents of all CPU register are saved in a designated area of MDXDEBUG RAM called the Register Map. In the Register Map, the register contents may be examined or modified using the M command and a predefined mnemonic (or absolute address) of the storage location for that register (example :PC, :A, , :SP). The Register Map is also used to initialize the CPU registers whenever execution is initiated or resumed. Thus the E and B commands can be used together to initialize, execute, and examine the results of individual program segments. The B command gives the user the option of having all CPU registers displayed when the breakpoint is encountered. This is done by entering a second operand to the B command. Otherwise DDT defaults to displaying the PC and AF registers. When all CPU registers are displayed, the format is the same as for the R command previously discussed. LOAD, DUMP, AND COPY (L, D, C) The Land D commands load and dump object files through the object I/O channel in standard Intel Hex format. Checksums are used for error detection, and the addresses of questionable blocks are typed automatically while loading. The C command will copy the contents of the memory block specified to another block of memory. There are no restrictions on the direction of the copy or on whether the blocks overlap. HEXADECIMAL ARITHMETIC (H) The H command is a dummy command used to allow hexadecimal addition and subtraction for expression evaluation without performing any other operation. DDT I/O CAPABILITIES DDT specifies I/O channels, designated 'Console', 'Object', and 'Source', to which any suitable devices may be assigned. The Channel Assignment Table is located in MDX-DRAM where it maybe examined or modified using the M command. The table addresses correspond to the I/O channels and the table contents correspond to the addresses of the peripheral driver routines. A channel which has a device assignment may have that device assignment changed using the M command. This is accomplished by merely modifying the table contents of that channel's table address to correspond to the new peripheral driver routine. A set of peripheral driver routines is supplied and listed below. This scheme also allows the user to write a driver routine for his own peripheral, load it into memory, and easily configure that peripheral into the system. DDT-SO I/O PERIPHERAL DRIVERS 1. A serial input driver (usually a keyboard). 2. A serial output driver (usually a CRT or teletype typehead). 3. A serial input driver wh ich sends out a reader step signal (usually a teletype reader). 4. A serial output driver which forces a delay after a carriage return (usually a Silent typehead). 5. A parallel input driver (usually for high speed paper tape input). 6. A parallel output driver (usually for high speed paper tape output). 7. A parallel output driver (usually for a line printer). TEXT EDITOR DESCRIPTION The Text Editor permits random access editing of ASCII character strings. It can be used as a line or character oriented editor. Individual characters may be located by position or context. The Editor works on blocks of characters which are typically read into memory from magnetic tape or paper tape. Each edited block can be output to magnetic tape or paper tape after editing is completed. While the primary application for the Text Editor is in editing assembly language source statements, it may be applied to any ASCII text delimited by "carriage returns". The Editor has a macro command processing option. Up to two sets of commands may be stored and processed at any time during the editing process. All I/O is done via the DDT channels. The Editor can be used with the MOSTEK ASMB Assembler and Loader to edit, assemble, and load programs in memory without the need for external media for intermediate storage. The following Editor: AnBn Cn dS1dS2dDnE- 1Ln Mn N- Pn - RSn dS1d- commands are recognized by the Text Advance record pointer n records Backup record pointer n records Change string S1 to string S2 for n occurrences Delete next n records Exchange current record with records to be inserted I nsert records Go to line number n Enter command buffers (pseudomacro) Print top, bottom, and current line number Punch n records from buffer Read source records into buffer Search for nth occurrence of string S1 29 ASSEMBLER DESCRIPTION The Assembler reads Z80 source mnemonics and pseudo-ops and outputs an assembly listirig and object code. The assembly listing shows address, machine code, statement number, and source statement. The object code is in industry standard hexadecimal format modified for relocatable, linkable assemblies. The Assembler supports conditional assemblies, global symbols, relocatable programs, and a printed symbol table. It can assemble any length program, limited only by a symbol table size which is user selectable. Expressions involving addition and subtraction are allowed. A global symbol is categorized as "internal" if it appears as a label in the program; otherwise it is an "external" symbol. The printed symbol table shows which symbols are internal and which are external. The Assembler allows the user to select relocatable or non-relocatable assembly via the "PSECT" pseudo-op. Relocation records are placed in the object output for relocatable assemblies (the MOSTEK object format is defined below). The Assembler can be run as a single pass assembler or as a learning tool. (In this mode, global symbols and forward references are not allowed). The following pseudo-ops are recognized by the Assembler: ORG program origin EQU equate label DEFL define label DEFM define message DEFB define byte DEFW define word DEFS defi ne storage END end statement NAME program name definition PSECT program section definition GLOBAL global symbol definition Supports the following assembler pseudo-ops EJECT eject a page of listing TITLE place heading at top of each page LIST turn listing on NLiST turn listing off RELOCATING LINKING LOADER DESCRIPTION The MOSTEK Relocating Linking Loader provides state-of-the-art capability for loading programs into memory by allowing loading and linking of any number of relocatable and non-relocatable object modules. Non-relocatable modules are always loaded at their starting address as defined by the ORG pseudo-op during assembly. Relocatable object modules can be positioned anywhere in memory at an offset add ress. 30 The Loader automatically links and relocates global symbols which are used to provide communication or linkage between program modules. As object programs are loaded, a table containing global symbol references and definitions is built up. At the end of each module, the loader resolves all references to global Symbols which are defined by the current or a previously loaded module. It also prints on the console device the number of defined global symbols that have been referenced. The symbol table can be printed to list all global symbols and their load address. The number of object modules which can be loaded by the Loader is limited only by the amount of MDX-RAM available for the modules and the symbol table .. Space for the symbol table is allocated dynamically downward in memory from either the top of memory or from a specified address entered as an operand of the load command. All I/O is done via the DDT channels. Assemblies can be done from source statements stored in memory (by the Editor). The object output can be directed to a memory buffer rather than to an external device. Thus, assembly and loading can be done without external storage media. The Loader prints the beginning and ending address of each module as it is loaded. The transfer address as defined by the END pseudo-ops is printed for the first module loaded. The Loader execute command (E) can be used to automatically start execution at the transfer address. The Loader Commands are the following: L offset load object module at address "offset" plus program origin address E execute loaded program at transfer address of first module T print global symbol table MOSTEK OBJECT OUTPUT DEFINITION Each record of an object module begins with a delimiter (colon or dollar sign) and ends with carriage return and line feed. A colon (:) is used for data records and the end-of-file record. A dollar sign ($) is used for records containing relocation information and linkirig information. All information is in ASCII. Each record is identified by "type". The type is determined by the 8th and 9th bytes of the record which can take the following values: 00 01 02 03 04 05 - data - end-of-file - internal symbol - external symbol - relocation information - module definition rOW"'' " 1 ·· 2 # of BINARY 3 RECORD TYPE 4 5 6 7 II 8 9 0 START ADDRESS OF DATA DATA BYTES 0 0 CHECK SUMG) ..• DATA•.• I ·· 0 TRANSFER ADDRESS OF MODULE 0 0 I I.. 0 • 0 0 0 MODULE NAME I CHECK SUMG) LINK AD~RESS0 I 4 0 .

MD SERIES MICROCOMPUTER MODULES zao Single Step Module (MDX-SST) FEATURES o Hardware single-step capability o Compatible with DDT Operating System STD-Z80 BUS compatible o DESCRIPTION The MD Series andtheSTD BUS were designed for lowcost OEM microcomputer modules. The STD BUS uses a motherboard interconnect system concept and is designed to handle any MD Series Card type in any slot. The modules for the STD BUS are a compact x inches which provide for system partitioning byfunction (RAM, EPROM, 1/0). This smaller module size makes system packaging easier, while increasing MOS-LSI densities provide high functionality per module. The MD Series of OEM microcomputer boards and the STD BUS offer the most cost-effective system configuration available to the OEM system designer. MDX-SST DESCRIPTION The MOSTEK MDX-SST was designed to enhance the hardware and software debug capability for MD Series systems. The use of the MDX-SSTwith the MDX-CPU1 and MDX-DEBUG boards allows the user to single-step instructions through RAM andlor EPROM/ROM with the capability of displaying all of the MDX-CPU 1 registers on each instruction execution. The MDX-SST board is implemented using the MDXCPU1 's nonmaskable interrupt and is controlled by firmware from the keyboard. When the command to single step an instruction is given, the sequence of events is the same as executing a program except that a "1" is output to the single step control port (DFH) instead of a "0". The circuit decodes the double M 1 instructions (CBH, DDH, EDH, or FDH) and M 1 is used to clock a shift register circuit which (if a "1" is output to port DFH) generates a nonmaskable interrupt at the start of the instruction to be single stepped. The nonmaskable interrupt saves the address of execution on the stack and causes the next instruction to be fetched from address EH. The shift register is clocked twice after the nonmaskable interrupt, causing the signal DEBUG to go low, forcing "E" on the most significant address lines, and causing the instruction to be fetched from the EH in the operating system DDT The operating system then jumps to EH, clears the debug flip-flop by reading PORT DFH, saves the MDX-CPU1 registers in the MDX-CPU1 scratch RAM, and waits for the next command. The single-step command is implemented in DDT which resides on the MDX-DEBUG board and has the following format: S COMMAND, Single-step This command allows the user to start single-stepping from a given location for a given number of instructions and to display the CPU registers after each step. Format: .S aaaa,nn,b(cr) .S aaaa,nn (cr) .S aaaa (cr) .S (cr) start single-stepping at location aaaa for nn steps or instructions. If b=O, display only the PC and AF registers, if b#O, display all the CPU registers. the same as above with b = 0 assumed. the same as above with nn= 1 and b=O assumed . the same as above with nn= 1 and b=O assumed; aaaa is set equal tothe contents of the user's PC. The use of the MDX-SST board requires the MDX-CPU1 and the MDX-DEBUG.

The STD BUS uses a mother board interconnect system concept and is designed to handle any MD Series Card type in any slot. The modules forthe STD BUS are a compact x inches which provide for system partitioning by function (RAM, EPROM, 1/0). This smaller module size makes system packaging easier while increasing MOS-LSI densities provide high functionality per module. The MD Series of OEM microcomputer boards and the STD BUS offer the most cost-effective system configuration available to the OEM system designer. On-board memory is provided in the form of 4K of EPROM ('s) and bytes of scratchpad RAM as pictured in the block diagram. In addition, a MK Counter Time Circuit is included on the MDX-CPU1 to provide counting and timing functions for the Z Either EPROM can be located at any 2K boundary within any given 16K block intheZ80 memory map via a jumper arrangement. The MDX-CPU1 can be used in conjunction with the MDX-DEBUG and MDX-DRAM modules to utilize DDT80 and ASMB in system development. This is accomplished by strapping the scratchpad RAM to reside at location FFOO so that it will act as the Operating System RAM for DDT MDX-PROTO DESCRIPTION HARDWARE DESCRIPTION MDX-CPU1 DESCRIPTION The MOSTEK MDX-CPU1 is the heart of an MD Series Z80 system. Based on the powerful Z80 microprocessor, the MDX-CPU1 can be used with great versatility in an OEM microcomputer system application. This is done simply by inserting custom ROM or EPROM memories into the sockets provided on the board and configuring them virtually anywhere within the Z80 memory map. The MDX-CPU1 is also available in 4MHzversion (MDXCPU 1 -4). In this version, one wait cycle is automatically inserted each time on-board memory is accessed by a read or write cycle. This is necessary to make the access times of the PROMs and the scratchpad RAM compatible with MK 4MHz ZSO-CPU. MDX-DRAM DESCRIPTION The MDX-DRAM is designed to be a RAM memory expansion board for the MOSTEK MD SERIES of ZSO based microcomputers. It is available in three memory capacities: SK bytes (MDX-DRAMS), 16K bytes (MDX- 37 BLOCK DIAGRAM MDX-PROTO STD zeo BUS ("_I08·~ZK.'16·1,II( ,uMoSI6-f( L:=>
