CHAPTER 1

INTRODUCTION

Congratulations on your purchase of a KIM memory expansion board. It

has been carefully engineered to provide high reliability and a long service

life. Please make sure you take a few minutes and read this User’s Manual

completely. You will then be familiar with all the features of your memory

expansion board and will find it easy to connect the board to your existing

KIM-1 System.

A single memory expansion board may be wired directly to your KIM-1.

By using the KIM-4 motherboard you may add additional memory modules to expand

your memory space by an additional 58,000 bytes.

Like all MOS Technology, Inc. microprocessor modules, your memory

expansion module is completely assembled and tested. Even if you are not using

a KIM-4 motherboard, all you will have to do is wire a simple cable. Your KIM

memory expansion module is covered by a complete 90-day warranty and, like all

KIM modules, factory repair services are available even after the expiration

of your warranty.

Your KIM memory expansion board has its own +5v regulator and requires

only 8 to 10 VDC unregulated for satisfactory operation. If you already have a

regulated +5v supply, you may use it with your expansion board and bypass

the regulation circuitry.

All the necessary circuitry has been included to make your memory expansion

module completely compatible with KIM-1. By setting the switches on the memory

expansion board, you can select the address locations in memory where you wish

your expansion memory to reside.

2

The integrated circuit memories used on your board are high-speed

static memory modules. No refresh cycles are required and access to this

memory will not require any slow-down of your KIM-1.

Chapter 2 of this manual explains how to install your new memory

expansion module in your KIM system. Chapter 3 explains how to check out

your memory expansion module and how to test it if you ever suspect that is has

failed. Chapter 4 contains information on your memory expansion module warranty,

and Chapter 5 explains the theory of operation. If for any reason you are

unable to get your memory expansion module operating satisfactorily, follow

carefully the checkout instructions in Chapter 3. If you are still unable

to get satisfactory operation, return the module as described in Chapter 4

or contact the manager of KIM Customer Support at MOS Technology, Inc.

corporate headquarters, 950 Rittenhouse Road, Norristown, Pennsylvania 19401.

CHAPTER 2

INSTALLATION

2.1 INTRODUCTION

How you install your KIM memory expansion module will depend on whether

or not you are using a KIM-4 motherboard to interface your expansion module to

KIM-1. The pin configuration on your KIM-2 or KIM-3 allows you to plug your

memory expansion module directly into the KIM-4 motherboard and begin operation

immediately. You may insert as many KIM-2 or KIM-3 memory expansion modules

into the motherboard as you wish, taking care that each is set to a different

memory location. If, however, you are connecting your memory expansion module

directly to KIM-1, only one KIM-2 or KIM-3 may be connected in this manner.

In this case you will have to wire a cable for your memory expansion module

which connects to the KIM-1 expansion and application connectors. (See Figure 1)

2.2 CONNECTING YOUR MEMORY EXPANSION MODULE TO THE MOTHERBOARD (KIM-4)

If you have already installed a KIM-4 motherboard in your KIM system, it

is only necessary to plug the KIM-2 or KIM-3 into any slot on the motherboard.

Make sure that your motherboard power supply has sufficient capacity to supply

the needs of your memory expansion module. See your KIM-4 User Manual for power

supply connections. The KIM-2 4K memory expansion module draws 1.5A and the

KIM-4 8K memory expansion module draws 3.0A. Your KIM memory expansion module

should be inserted in the motherboard so that the component side of the board faces

away from the end of the motherboard to which KIM-1 is connected. Prior to inserting

the memory board in the motherboard set the address switches located on the memory

board to the correct position for the address in K IM’s memory space where you wish

to have the additional memory reside. Setting the address switches is described below.

When the memory switches are set and the card is inserted in the motherboard

you are ready to check out the operation of the board. See Chapter 3 for this

operation.

2.3 CONNECTING YOUR MEMORY EXPANSION MODULE WITHOUT A MOTHERBOARD

If you are connecting your memory expansion module directly to a KIM-1,

it will be necessary for you to wire a cable to connect the memory expansion

module connector to the application and expansion connectors on your KIM-1.

Note that if you wish to use the same +5v supply which presently powers your

KIM-1, that supply should be connected to pin 21 and pin Y on your memory expansion

module connector. If, however, you wish to use an unregulated +8v to +10v supply,

that unregulated voltage should be connected to pins 19 and 20 on your memory

expansion module. Unregulated +8vto +10v should never be connected to your KIM-1.

In either case, insure that your supply can provide at least 1.5A for KIM-2 or

3.0A for KIM-3.

Table 2A and 2B show the interconnection between KIM-1 and your memory

expansion module. If you do not have the appropriate connectors for the KIM-1

expansion connector and your KIM-2 or KIM-3 memory expansion module, they can be

obtained from most electronic parts supply houses. They are manufactured by

Vector and their part number is R644. Note that the pin designation is marked

next to each pin on the connector. Once you have wired the cable interconnecting

the three connectors, carefully recheck your wiring for incorrectly placed wires

or inadvertant short circuits. Note that the wiring table shows the pins on the

KIM-1 connectors are preceded by an "A” or "En. The "A" indicates that the

connection should be made to the appropriate pin on the applications connector;

the ”EM indicates that the pin is on the expansion connector.

2.4 SETTING THE ADDRESS SWITCHES

In order to make your memory expansion module as versatile as possible,

we have included four switches to allow you to place your expansion memory

at any memory address. (See Figure 3) We suggest that you place your first

memory expansion module starting at address 2000jlex and continue to expand your

memory into successively higher memory locations. Tables 4 and 5 indicate the

switch settings for various memory locations using your KIM-2 or KIM-3. Be sure

to consult the appropriate table for the module you have purchased. Once you

have chosen the memory space for your expansion module and correctly set the

addressing switches,turn off all power and insert the memory module in its

connector. You are now ready to test your memory expansion module.

Note: Do not set the switches so that your expansion memory has

an address below 2000jiex as it will conflict with the memory

and other circuitry in your KIM-1. It is not possible to put

your expansion memory in the memory block 0400-1400^^ already

decoded on KIM-1.

CHAPTER 3

CHECKOUT AND TEST PROGRAM

3.1 Your memory expansion module has been carefully tested to assure

correct operation. In this section we will describe how you can briefly check

the operation of your memory expansion module. We have also included a test

program which will allow you to verify correct operation of all memory cells

in your memory expansion module. It should only be necessary to run this

program if you suspect that the memory module has failed.

To verify that your memory expansion module has been correctly wired and

that the address switches are correctly set, just address some of the memory

locations and verify that you can change the contents of those locations.

Using the keypad provided with your KIM-1, and assuming that you have set the

address switches on your memory expansion module so that the lowest address

is 2000, use the following procedure:

If you are unable to change the (

sources of trouble:

1. The memory expansion board is not correctly connected to KIM-1.

If you are using a motherboard, check that the motherboard is correctly installed

and that, the memory expansion card has the component side of the board facing

in memory there are two possible

wiring against the list provided in Table 2A and 2B.

2. You have incorrectly set the memory address switches. The

figure below shows the appearance of the memory address switch when it is

configured so that the lowest expansion memory address is 2000ig. Recheck

the information in Chapter 2 if you are unsure of the placement of the

memory expansion module.

5.2 TEST PROGRAM FOR MEMORY CHECKOUT

Although your KIM memory expansion module has been carefully tested

before shipment, like any other electronic device, it can fail in use. If you

suspect that your memory expansion module is not working correctly, the following

program can be used to check the memory operation. It should be noted that

programs for testing memory modules for all possible failure modes would be

quite complex and require lengthy running time on KIM. The following programs

simply write and read every possible bit pattern in every memory location.

They do not check, for instance, whether writing to a given memory location

may also affect other memory locations.

3.3 CHECKING YOUR MEMORY FROM A TERMINAL

The following program assumes that you have a terminal connected to the

serial input and output ports of your KIM-1. To use the program, type it into

KIM memory starting at location 200ig; make a paper tape copy once you have

loaded the program using the KIM dump routine. To operate the program, load

the lowest address which you wish to test in location OODl and 0002, then load

the highest memory address you wish to test in location 0003 and 0004. For

instance, to check all memory locations between 2000 and 2FFF you would load 00

in location 0000, 20 in location 0001, FF in location 0002, and 2F in location 0003.

To operate the program, load address 022A and hit the G key. The program will

then fill the specified memory locations with 0's and then read all locations

to verify that the zero has been written. It will then load the specified memory

with 01 and again verify the data. The process will continue until all bit patterns

from 00 to FF have been written and read correctly. If any memory location

fails to read or write correctly the address of the defective cell will be

written to the terminal, along with the code which would not read or write

correctly. When all bit patterns have been tested in all specified cells, the

program will output a carriage return and line feed and begin the entire

cycle over again. For a 4K memory expansion module the entire test will take

about 1% minutes.

3.4 CHECKING MEMORY OPERATION WITH THE KEYPAD

Program 2 tests memory in a similar fashion, but does not require a

terminal. As in the first program, the address of the lower limit and upper

limit of the memory to be checked is inserted in locations 0 through 3. When

the program has been keyed in, you will probably wish to record it on your

audio cassette for future use. When the starting address (022E) is loaded and

the GO button is depressed the program will check memory as described above.

However, if a defective cell is encountered the address of the defective cell will

be displayed on the leftmost four digits of the display and the program will halt.

Pushing any button on the keypad will resume the testing operation. When all

memory cells have been checked, a value of 0000 will appear in the display and

the program will halt.

CHAPTER 5

THEORY OF OPERATION

5.1 The t'wo schematics show the interconnection of the components

on the KIM-2 and KIM-3 boards. The diagram below illustrates the pin

connections to the 2102-type memories used on the boards. When the ENABLE

line is low, one of the 1024 bits in the package is selected. If pin 3 is

high, the selected cell will have the value of the DATA IN line (1 or 0)

written into it. If Pin 3 is low, the contents of the addressed cell will

be placed on the DATA OUT line.

The boards are composed of the memory circuits, addressing circuitry,

and buffers. An on-board voltage regulator is also provided. The following

description applies to the KIM-2 board; KIM-3 differences are noted at the end.

In operation, address bus lines 0 through 9 are buffered by U4, U5, U8,

and U9, and connected directly to the memory circuits. The high-order address

lines (AB12 - 15) are presented to U15, a 4-bit comparator. The bit pattern on

these lines is compared with the bit pattern generated by the four address switches.

If the address switch settings and the high-order address lines match, pin 6 of

U15 will go high. This signal is inverted twice in Ull and passed off the board

as the BD SELECTED line. When BD SELECTED goes high it disables U4 on KIM-1,

preventing the memory circuits on KIM-1 from conflicting with addresses

intended for the expansion memory board.

Address bus lines 10 and 11 are decoded in U6 to provide four output

lines (pins 4, 5, 6, and 7). Each of these four lines is connected to a group

of eight memory circuits to determine which bank of memory circuits will be

active at any time. U6 will not be activated unless the proper address

configuration exists on address bus pins 12 - 15. The BD SELECTED line is

used to enable U6. The comparison signal from pin 6 of U15 is also used in U7

to combine with the 02 and R/W signals from KIM-1 to control the input and

output buffers (U12 and U13).

The effect of this circuitry is such that when the high order address

bits match the switch settings, U6 and U7 are enabled to decode address bits 10

and 11; when clock phase 2 is present the data bus buffers will be enabled,

allowing data to be fed into or out of the board, depending on the condition

of the Read/Write line. U6 will enable the appropriate bank of memory circuits

and the selected memory circuits will decode the ten least significant address

bits to complete the Read/Write operation.

U16, Ql, and Q2 and their associated circuitry from a conventional

series regulator which take the unregulated +8v supplied to the board and

supply a regulated +5v for the circuitry.

The only difference between the KIM-2 and KIM-3 circuitry is that U6 now

decodes three address lines (AB10 - 12) and U17 decodes three address lines

(AB13 - 15). U6 now controls which of eight memory banks is selected. Additional

drivers are provided for AB0 - 9 to supply the extra drive needed for the increased

number of memory circuits.
