PACMAN MULTI KIT INSTALLATION INSTRUCTIONS
Steps for a successful install of your online or offline high score save
kit -
Ensure your gameboard is working 100% before installing kit
Ensure power to game is off before removing your gameboard from
cabinet
Label any connectors that you will be disconnecting. This will make
reinstalling easier once kit is on gameboard
Note which way your edge connector is on. We suggest taking
pictures to help you remember!
Work in a well lit area on your workbench
The Pacman Multi Kit contains -
1 Pacman Multi Kit
1 CPU 40 Pin flat cable
1 GFX multiboard (for location 5E)
3 Prom multi-Boards (for locations 7F, 4A and 1M)
1 28 pin socket

1. Remove the game board and locate the sync bus daughter board
(some versions of Pacman have a custom IC instead of the syncbus
daughter board, in this case skip step 3)

2. Cut the cable tie and carefully remove the sync bus daughter board
3. Remove all program roms (location 6E-6P (on the pic above, only 6E-6J
are filled with roms)
4. Remove all GFX-Roms at location 5E and 5F (Recommendation - label
the eproms before removing)
5. Remove the PROM at location 7F (recommendation: label the prom
before removing)
6. Remove the PROM at location 4A (recommendation: label the prom
before removing)
7. Remove the PROM at location 1M (recommendation: label the prom
before removing)
8. Remove the Z80 CPU at location 6B
(If you have a MS pacman board, remove the original 40pin flat cable)

After removing all the parts above, the the pcb should look like this -

9. Carefully insert the 40pin flat cable connector (DIL) into the socket of the
Z80 CPU
- make sure that the flat cable points to the CPU edge connector (see pics
below)

10. Insert the PROM Board labeled with 7F in the socket located at 7F
(see pic below)
Make sure that the pins fit the socket and the 10pin jack is facing to the
gameboard edge connector

11. Insert the PROM board labeled with 4A into the socket located at 4A
(the 10pin jack must point towards the edge connector of the game board)
12. Insert the PROM board labeled with 1M into the socket located at 1M
(the 10pin jack must point towards the edge-connector of the game board)

13. Insert the gfx-board into location 5E.
Make sure that the pins fit in the socket. Attention: the 10pin jack is at
the opposite side compared with the prom boards!

14. Your pacman pcb should look like this now. Please check if the 10pin
jacks are facing like shown in the pic below

15. Insert the 28pin socket into the empty socket at location 6D
(where the sync bus board was before)
16. Carefully insert the sync bus board into the double socket at location
6D.
Make sure that the pins fit into the socket. Attention: The notches of the
IC on the syncbus board must face towards the gfx board.
In some cases, the pins of the sync bus board hit the top of the eprom of
the prom board at location 7F. In this case, I suggest to push the prom
board softly to the right (see pic below) while pushing the sync bus board
into the socket.

17. Secure the sync bus board from falling off with a cable tie.

18. Get the 5 pin flat cable and identify the first 10pin plug. See pic below.

19. Insert the first plug into the jack on the save kit pcb

Now insert the CPU into the multi kit.
Make sure that the pin 1 of the cpu match the pin 1 of the socket of the
savekit (see pics below)

20. Insert the 40 pin flat cable plug into the jack of the multi kit. (see pics
below)

21. Insert the 2nd 10pin plug of the flat cable
(Start counting from the save kit pcb) into the jack of the prom board 7F
(see pics below).

22. Insert the 3rd 10pin plug into the prom board at location 4A
23. Insert the 4th 10pin plug into the gfx board at location 5E
