Here are the pinouts to Super Pac-Man.  The first part of this file contains

original information pulled from the manual.  At the end of this file, Scott

Lemon was kind enough to test the pinouts and he gives the minumum set of pins

needed to get the game to actually work.

Super Pac-Man pinouts

Midway, December 1982

 

There are three boards to the Super Pac-Man boardset:

   CPU Board         A084-91436-D316

   Video Board       A084-91435-C316

   Credit Bypass Bd  A082-91348-0000

 

The CPU board is labeled with:

      [@ location 2M]

      c1982 BALLY MIDWAY MFG. CO

         ALL RIGHTS RESERVED

      [@ location 3K]

      A084-91436-F316

      [@ location 4J]

      SUPER PAC-MAN CPU BD.

 

And the video board is labeled with:

      [upside down, @ location 5L]

             VIDEO P.C. BD

             SUPER PAC-MAN

            A084-91435-D316

      c1982 BALLY MIDWAY MFG CO.

         ALL RIGHTS RESERVED

            PATENT PENDING

 

I do not know if the credit bypass board has any distinguishing features or

not.  The diagrams do not show the board.

 

The CPU board has a 9-pos connector at label J1, a 20-pos connector at label

J2, and a 10-pos connector at location J3.

 

The video board has an 11-pos connector at label J1.

 

The credit bypass board has a 7-pos connector.

 

Legend:

CP = Control Panel

PS = Power Supply

Cred = Credit Bypass Board

CPU = CPU Board

 

The game is powered using these supply outputs:

+5V DC          @ 4A

+5V DC (UNREG)  @ 2A     [coin meter only]

-5V DC (-SENSE) @ 0.45A

+12V DC         @ 2A

 

 

Here are the pinouts for the CPU, Video, and Credit Bypass boards:

J1 CPU Board (9-pos)

Pin | Definition

------------------

  1 | Not Used

  2 | Gnd (to speaker)

  3 | Speaker

  4 | Key

  5 | Not Used

  6 | P2 Down

  7 | P2 Left

  8 | P2 Up

  9 | P2 Right

 

J2 CPU Board (20-pos)

Pin | Definition

------------------

  1 | P1 Down

  2 | P1 Left

  3 | P1 Up

  4 | P1 Right

  5 | Not Used

  6 | Service

  7 | Coin Meter (and to Cred/4)*

  8 | Not Used

  9 | Key

 10 | P2 Start

 11 | P1 Start

 12 | P2 Fast

 13 | P1 Fast

 14 | Tilt (and to Play/Test switch)**

 15 | Gnd (to CPU/J3-3)

 16 | (from Cred/7)

 17 | Not Used

 18 | Not Used

 19 | Not Used

 20 | Not Used

 

* Note: It looks to me like pin 7 is inverted before it reaches the Coin

Meter or Credit Bypass board pin 4.  The symbol used is "-->|".  The ">"

is a triangle.  On the other side of the coin meter, the diagram shows

the trace going to UNREG +5V on the power supply.

 

** Note: Tilt shares it's ground with coin switch 1, coin switch 2, and

Cred/3.  Also, pin 14 goes to a Play/Test switch (I don't recognize the

symbol for this switch), which gets its ground from CPU/J3-2.  I assume

this Play/Test switch is the kind where you pull it out to put the game

into test mode.

 

J3 CPU Board (10-pos)

Pin | Definition

------------------

  1 | Gnd (to PS and from CP common ground)

  2 | Gnd (to PS and from Play/Test switch)

  3 | Gnd (to PS and from CPU/J2-15)

  4 | -SENSE (to PS)

  5 | +12V (to PS)

  6 | Key

  7 | +5V (to PS and from Cred/6)

  8 | Not Used

  9 | +5V (to PS and from CPU/J3-10)

 10 | +5V (to CPU/J3-9)

 

J1 Video Board (11-pos)

Pin | Definition

------------------

  1 | Shield*

  2 | Comp Sync (-)

  3 | Comp Sync (-)

  4 | Key

  5 | Gnd

  6 | B

  7 | Gnd

  8 | G

  9 | Gnd

 10 | R

 11 | Gnd

 

* Note: There is a note about the shield that says, "pined at logic; out at

monitor jack".  I have no idea what the shield is for.

 

Credit Bypass Board (7-pos)

Pin | Definition

------------------

  1 | Coin Sw#1

  2 | Coin Sw#2

  3 | Gnd (to PS/16)

  4 | (from CPU/J2-7, inverted, and to Coin Meter)

  5 | Key

  6 | +5V (to CPU/J3-7)

  7 | (to CPU/J2-16)*

 

* Note: the Credit Bypass board schematic shows pins 1, 2, and 4 as being

on the same trace.  I have a feeling that CPU/J2-16 can just be considered

the Coin Switch pinout if you don't have a Credit Bypass board.

 

I don't really feel like labeling all the power supply (A082-90421-0000)

pinouts.  But I had already written this information down since I was

referring to it in various places of the schematics, so here it is:

 

Power Supply (22-pos)

1   Audio Circuit, unreg filtered

2   -5V/0.45A

3   +12V [to coin door and control lights/2A, unreg aux., V.]

4   Reset

5   V.Batt

6   Key

7   +12V/2A

8   +12V/2A [connected to 7]

9   -SENSE

10  AC SYNC

11  Gnd [control lights return]

12  Audio Circuit [connected to 11]

13  Gnd

14  Gnd

15  Gnd

16  Gnd [from Cred/3]

17  Counter Drivers (~8V, unreg +5V) [from coin meter]

18  +5V/4A

19  +5V/4A [connected to 18]

20  Key

21  +5V/4A [connected to 18]

22  +5V/4A [connected to 18]

 

Feel free to correct any misinformation you find in this pinout.  If you

let me know (holcomb@halcyon.com), I will correct the copy of this pinout

located on wiretap.spies.com.

Hi Dave,

 

I finally got all my Molex connectors I was waiting for, so I got to wire

up my Super Pacman this weekend! And it works, with a few minor mods to

your pinout. The only problem was getting around the coin bypass board,

which wasn't difficult. Anyway, here is the amended info, you might want

to merege it with the one you sent me.

 

Super PacMan Wiring Notes

 

Scott Lemon, 12/2/95   (slemon@jolt.mpx.com.au)

 

 

1. The credit bypass board is not required to get Super PacMan running.

J2-8 appears to be the coin pin, although it is marked "Not Used" on your

pinout. J2-15 has no effect as a coin pin.

 

2. I used Molex 0.156" crimp terminal housings to wire up a harness,

these worked well. I wouldn't recommend soldering directly to the pins

unless you were desperate.

 

3. Not all the pins need to be connected to work. Looking at the traces,

 many appear to be common. The following pinout works correctly:

 

 CPU Board

 ---------

 

 J1-2  Speaker Ground

 J1-3  Speaker

 

 J2-1  Joystick Down (Player 1)

 J2-2  Joystick Left (Player 1)

 J2-3  Joystick Up (Player 1)

 J2-4  Joystick Right (Player 1)

 J2-8  Coin

 J2-10 Player 2 Start

 J2-11 Player 1 Start

 J2-13 Player 1 Fast

 J2-15 Ground - looped over to J3-3

 

 J3-1  Ground

 J3-2  Control Ground  (this was spare so I used it)

 J3-3  Ground - looped over to J2-15

 J3-4  -5V

 J3-5  +12V

 J3-7  +5V

 

 Video Board

 -----------

 

 J1-1  Coin Ground  (this was spare so I used it)

 J1-2  Composite Sync (-)

 J1-6  Blue

 J1-8  Green

 J1-10 Red

 J1-11 Video Ground
