CHAPTER 2 HOW TO ASSEMBLE THE KIT 2-1 GENERAL Don't unpack your parts yet. Do a little reading first, and you may save yourself time and expense. I CAUTION I The metal-oxide-semiconductor (MOS) devices in this kit are susceptible to static electricity. Do not remove them from the protective, black foam backing sheet until you have read the precautions and instructions in paragraph 2-4. way, there won't be any surprises later. Take your time.
2-3 SELECTING TOOLS AND MATERIALS These tools and materials will be required to assemble the kit: o o o o o Needle-nose pliers Sma" Phillips screwdriver Small diagonal cutters Soldering pencil, not more than 30 watts, with extra-small-diameter tip. (1/16 in. isn't too sma".) You should also have a secure holder for it. Rosin-core solder, 60:40 (60% tin), sma" diameter (,05 in, or less) wire Note: o M PHILLIPS SCREWDRIVER NEEDLE-NOSE PLIERS SOLDE~ Soldering paste is not needed.
2-4 UNPACKING AND SORTING PARTS The MCS-85 System Design Kit is shipped skinpacked on a card that includes a conductive backing to protect its metal-oxide-semiconductor (MOS) devices from static charge. Don't remove the four larger-size I ntel devices from the foam backing until you have completed all of the instructions in this chapter and are ready to place them on the board.
Next, open the bag of electrical parts and sort them out by type and value. Give yourself plenty of unobstructed work space and try not to let tiny parts skitter away from you.

The easiest method of doing this is to insert each button in its turn, bend its leads over on the back of the board to hold it in place, and go on until all buttons are in place, then solder all of them in one pass, with the board lying flat on the work surface and weighted down to make sure the switches are uniformly held firmly against the front surface of the board. 0 2·16 Install the twenty-four pushbutton switches that make up the keyboard.
CHAPTER 3 FINAL ASSEMBLY AND CHECKOUT 3-1 GENERAL Now that most of the components are soldered on your circuit board, it's time to give your handiwork a quick visual check to make sure all of the devices are oriented correctly. The notched ends of the I Cs should all be toward your left, and the decimal points of the LED displays should be at the bottom line of the characters.

I CAUTION I Large-scale integrated circuits are fragile! Dropping, twisting, or uneven pressure may break them. The discharge of static electricity can destroy them internally. Leave them embedded in the conductivefoam backing sheet until ready to install on the board. Never press down hard upon, twist, or bend the larger devices. Touch the exposed metal traces of the board with your hand before inserting one in its socket. The soldering of large devices directly on the circuit board is not recommended.
3-6 WHAT IF IT DOESN'T? If there is no response to the 8 command, D Use the multimeter to check for the presence and proper polarity of +5 Volts on the board. D Check all of the strapping connections, and be sure they are in the right places for the configuration you chose. D Check carefully the seating of each and every pin of each of the four large ICs. Be sure no pins have accidentally bent over and missed the socket.
3-7 CONNECTING A TELETYPEWRITER If you wish to use a teletypewriter with your SOK-85 computer, connect it at Interface Connector J7 as shown in Table 3-5. You may use either a male connector or a female connector. (See Table 3-11.) Only four pins of this connector are assigned for Teletypewriter use; the remaining pins may be wire-wrapped to serve any function you choose.

CHAPTER 4 OPERATING INSTRUCTIONS 4-1 WHAT IT DOES The things you can do with the basic SDK-85 kit are: • Examine the contents of all memory and register locations • Deposit program steps or data in RAM or register locations ~ Execute programs command or subroutines upon i.e., only the last four or the last two digits entered wi II be accepted. As noted, the number system being used in the SD K-85 is the hexadecimal, or base-16 number system.
Whenever the monitor expects a command, the display shows a dash ("_") at the left edge of the address field (possibly along with an error message). When the monitor expects a parameter, a decimal point wili be displayed at the right edge of the field into which the argument will be placed. A parameter will be either an address or a byte of data which is used during the execution of a command. In the descriptions of the command modes, upper case letters and numbers enclosed in boxes represent keyboard keys.
Whenever the command changes the contents of a memory location, it also verifies that the change has occurred correctly. If the contents of the location do not agree with what the new value should be (i.e., if the memory location is in ROM or is nonexistent), an error message is generated. SUBSTITUTE MEMORY EXAMPLE 2 Using ~ to enter a small program: ADDR KEY DATA ~ MEM SUBSTITUTE MEMORY EXAMPLE 1 sing ~ MEM to U' locations: KEY list the first ADDR few Monitor DATA ~ MEM [I] ~ ~ ~ ~ El 0000.
Examine Registers: ~ B:J «data» B:J «data» TABLE 4-2 REGISTER DISPLAY SEQUENCE ... ~ KEY /DISPLA Y CODE The examine command allows you to display and modify the contents of the 8085 CPU registers. Pressing the·~ key blanks both the address and data fields, and displays a decimal point at the right edge of the address field. At this point, you must press a register key (register names are denoted by legends on the keyboard). Any other key will generate an error response.
EXAMINE REGISTER EXAMPLE 1 EXAMINE REGISTER EXAMPLE 2 Using ~ to initialize the 8085's stack pointer to 20C8: Using ~ to examine the contents of the 8085's Registers: KEY ADDR DATA ADDR KEY DATA ~ fExAMl ~ REG SPH ** 0 SPH 02. SPH 20. SPL ** SPL OC. SPl C8.
Go: o «address» ~ 0 Pressing the key causes the contents of the program counter (PCH and PCL) to be displayed in the addressed field, along with a decimal point at the right edge of the fieid. The program counter is available for change, and any number entered (a number is optional) becomes the new contents of the program counter. Pressing the ~ key transfers control of the CPU to the address in the address field (contents of the program counter).
GO COMMAND EXAMPLE Now you can execute the program you entered in Example 2 of the ~ command. First, check to make sure the 3- location program is in memory, then the program will be executed. Recall that this small program loads the A register with the nu mber 47 and restarts the monitor. To verify that the A register now holds 47 and to get more practice using ~ try the following sequence: KEY KEY ADDR DATA COMMENTS ADDR DATA COMMENT 47. A reg now I'EiAMl fSiiBsTl ~ ~ 0002. A holds 47.
Single Step: SJ~W «address» EJ EJ ... ~ Pressing the S~~~~E key causes the contents of the program counter (PCH and PCl) to be displayed in the address field of the display along with a decimal point at the right hand edge of the field. The data field contains the contents of the address denoted by the contents of the program counter. The program counter is made available for change, and any number entered (a number is optional) becomes the new contents of the program counter.
Vector Interrupt: G The @[J key is similar to the key in the respect that it takes control away from the monitor and gives it to another program. The interrupt key causes immediate recognition of RST 7.5 interrupt and control passes to location 3C in the monitor. This location contains an unconditional branch to instruction location 2004 in user RAM. You may place any instruction you wish in Locations 2004 thru 2006 (e.g., a branch to a keyboard interrupt routine).
The only command requiring an alphabetic parameter is the IIX" command. The nature of such parameters will be discussed in the section explaining the command. Display Memory Command, D: o , Selected areas of addressable memory may be accessed and displayed by the 0 command. The o command produces a formatted listing of the memory contents between and , inclusive, on the console.
Insert Instructions into RAM, I: I
Single instructions, or an entire user program, are entered into RAM with the I command. After sensing the carriage return terminating the command line, the monitor waits for the user to enter a string of hexadecimal digits (O to 9, A to F). Each digit in the string is converted into its binary value, and then loaded into memory, beginning at the starting address specified and continuing into sequential memory locations.SUDstitute Memory Command, S: X TABLE 4-3 COMMAND REGISTER IDENTIFIERS S
«data» IDENTIFIER The S command allows you to examine and optionally modify memory locations individually. The command functions as follows: 1. CODE Type an S, followed by the hexadecimal address of the first memory location you wish to examine, followed by a space or comma. 2. The contents of the location are displayed, followed by a dash (-).5. If a carriage return is typed in step (1) above, an annotated list of all registers and their contents is displayed. Note: The bits in the flag byte (F) and interrupt mask (I) are encoded as follows: Error Conditions - Invalid Characters Each character is checked as it is entered from the console. As soon as the monitor determines that the last character entered is illegal in its context, it aborts the command and issues an "*" to indicate the error.
CHAPTER 5 THE HARDWARE 5-1 OVERVIEW This portion of the SDK-85 User's Manual should provide you with sufficient knowledge to write programs to exercise the basic system as well as providing capability to use the basic kit as a nucleus around which you can build larger systems. Figure 5-1 is a functional block diagram of the SDK-85. The components enclosed in dashed boxes have places in the SDK-85 printed circuit board, but these are not needed for a minimum system and are not included in the kit.
The 8355 & 8755 The 8279 The 8355 and 8755 are two more chips specially designed for compatibility with 8085 systems. The 8355 contains 2048 bytes of mask programmed read only memory (ROM) and 16 I/O lines. The 8755 has an identical function and pinout to the 8355, but contains ultraviolet erasable and reprogrammable read only memory (EPROM) instead of the ROM. The 8279 is a keyboard/display controller chip that handles the interface between the 8085 and the keypad and LED display on the SDK-85 board.

5-7 CONVERTER CIRCUIT FOR RS232C SERIAL PORT If you are fortunate enough to have a CRT terminal that can operate at a 11 O-baud rate, and wish to use it with the SDK-85 computer, you may find that it is compatible only with RS232c" voltage-level serial ports and not with current loops. If this is the case, 1/ o Wire the MC1488 and MC1489 converter circuit (shown in Figure 5-5) into the wirewrap area of the SDK-85 board. o Remove R6, and connect the input line of the converter circuit to its lower pad.
CHAPTER 6 THE SOFTWARE 6-1 THE SDK-85 MONITOR The SDK-85 monitor program provides utility functions employing either a teletypewriter or the kit's on-board keyboard and display as console. The program resides in 2k (k = 1024) bytes of the ROM memory, between location 0 and location 7 F F. the routines that service each console device are independent; the two devices do not function simultaneously.
TABLE 6-1 MONITOR ROUTINE CALLING ADDRESSES Ca iii ng Address Mnemonic 07FD CI Description Console Input This routine returns a character (in ASCII code - see 8085/8080 reference card for codes) received from the teletype to the caller in the A register. The A register and CPU condition codes are affected by th is operation 07FA co Console Output This routine transmits a character (in ASCII code), passed from the caller in the C register, to the teletypewriter.
