IMPORTANT: Before you Start!

IF YOU HAVE NO EXPERIENCE IN CIRCUIT BOARD REPAIR, YOU SHOULD NOT TRY TO FIX YOUR OWN GAME! Before you start any circuit board repair, please review the excellent document at http://marvin3m.com/begin, which goes over the basics of circuit board repair. Most repair facilities will NOT repair your circuit board after it has been unsuccessfully repaired ("hacked") by you. If you aren't up to repairing your Pac-Man circuit boards yourself, ask for help either from myself or by posting to/ googling rec.games.video.arcade.collecting newsgroup for local help/recommendations.

AICA Bootleg Puck-Man

(Varient of Pac1 / Pac2)

Notable items of this board.

This board must mate with the left half of the Pac1 / Pac 2 ( Pac 2  PCB).  I'm only showing the unique half here.

This particular board is from Europe (Thanks to James G Watt http://www.kinetic-arts.demon.co.uk/  for the scan).
 

 

Bootleg Game Boards Non JAMMA Single PCB

Bootleg  Pac 3

     Notable Items of this board.


There are a few variations of this board family...

PAC3 is a Pac-Man board with only 8 EPROM sockets & MB3712 Audio Amplifier chip.  MP2621 board requires a jumper wire from 8E pin 13 to Z80 pin 5.

MPO1 is 2nd Generation Pac 3 with 8 sockets (or landings for sockets) in row 6 and 4 sockets in row 5.  This board is pre configured to run Ms Pac-Man bootleg software with wiring for the A15 to ROM Select circuitry.

To modify PAC3 4 socket row 5 to 2 2732s (from 2532s).

Cut pin 21 from 24 of 5F on back of board & Jump Pin 21 to 4E Pin 1.

** The associated componets (Capacitor/ Resistor) may not be on board, thus this pin may not work.  Often bootleg boards are hard wired for Cocktail Table mode.

 
 


Rock-Ola (Eyes) Bootleg

(Techstar - III)

Notable items of this board


My particular board is marked "TP-048, TECHSTAR-III, Miami 1982, Made in Japan" in Silkscreen.  There is a paper sticker obscuring the silk screen print.  On the paper sticker is printed "Rock-Ola C 1982 All Rights Reserved".  The paper sticker is also marked by hand "C6390-A".  The 2 sockets in row 5 should be filled with Maze/Charater ROMs.  Also this board has ROMs stacked in the 7H, 7J locations & wiring to hack this board to run as a Ms Pac-Man (bootleg).

GDP-01 (Japan?)

Notable items of this board
 


My particular board has no markings other than "GDP-01" & Asian text inside of 28 pin socket above Z80.

Variation of this board will use a piggyback board marked "GDP-02" which has a flying wire from main board 8B pin 11 to GDP-02 IC 4 pin 12.  This board may be replaced by a Sync Bus Controller board (without the flying wire).  I assume boards equipped with GDP-02 run non bootleg style software.
 

Sega Bootleg Pac-Man

Sega Pac-Man board


I've seen a one of these boards & have recieved pictures of 2 different boards.  On board did not have AC power supply section & had custom ICs (Namco?) at 5S & 6D.  The above board has unusual replacement boards for the custom ICs & has the AC power supply section stuffed.  It isn't visible in the picture but the board has "SEGA" in the copper trace, next to 5E/5F ROMs.

 

Odd Ball Bootleg Pac-Man #1



I appologize for the picture quality, this is all I have of this board and am GUESSING it is a Pac-Man.  The most unusual feature of this board is the Screen RAM in the lower left corner, a single chip turned perpendicular to the other chips (ala Galaxian).  If anyone has one of these boards please e-mail me!

Bootleg Pac-Man on Galaxian Hardware

Bootleg Galaxian Pac board

A port of Pac-Man to Galaxian's hardware exist.  This software must be of bootleg origin as it is commonly seen on a bootleg system board closely based on Galaxians hardware.  Notice in the screen shot below that the colors are different as is the screen proportions, Credit, Level & Lives remaining are incoporated in the Maze section (look at the middle exits).  The sound is also quite a bit different.

For pictures of the bootleg Galaxian Style board visit  http://thebrokenjoystick.com/pictures/gone-pac-cocktail-bootleg by BrianPipa.  Notice that this board uses a "cartridge" approach to software swapping.  This system also runs a few other games, all bootleg versions of orignal games such as Moon Cresta & The End to name a few.

There is also documentation on the web how to convert a Original Galaxian PCB to run the bootleg "galxian version of Pac-Man" software.  You can find that info at .... http://www.amug.org/~necro/video/.


 

Bootleg Game Boards JAMMA Single PCB

Bootleg Pac-Man JAMMA #1 (Zola Gal)

Notable items of this board

2 Versions of this board have surfaced.  One was marked "Made in Greece", which was found in Spain.  The above board is marked "FORCE ELECTRONICS" and is actually running Zola Gal software.  Notice the 4 dip switches above the ROM in the center of the board.  Zola Gal plays a time based game & 3 of these dips are for the time parameters, the 4th selects which version software you play, either Zola Pac Gal or Championship Edition which has no exits.  The 4th dip is attached to the highest address of the 27512 EPROM.  This board also has a 16V8 GAL that is protected.  The GAL reads the dips and interfaces to the databus and Z80 M1 lines.

Bootleg Pac-Man JAMMA #2


This board has a couple custom of PAL chips.  I've heard complaints that this board "seems" / "feels" / "sounds" a bit off in terms of play but I've yet to do a double blind test.

Bootleg Pac-Man JAMMA #3



Two-Bit Score made these.  The newest version has 2 edge connectors and may plug in either a JAMMA or ORIGINAL PAC-MAN harness.  Appears to have SRAM & the Two Bit Score software upgrades (16 in 1 Kit).  This board is no longer available due to copyright concerns.

Bootleg JY-PAC board

Bootleg Game Boards Emulation (JAMMA)

3 in 1 or 6 in 1 JAMMA boards w/ Pac

Three in 1 Board

 

The above photo shows the early series of this PCB which had a JAMMA connector attached to the main PCB via two ribbon cables.  Later versions of this PCB are a single board with the JAMMA connection part of the main motherboard.  This boardset is essentially the same from the early 3 in 1 games up to the current (1/2005) 39 in 1 games.  The board also support VGA monitor outputs and 4 pin HDD power connectors.  These boards are an emulation platform and run as many as 39 different games from Z80 based Pac Man & Galaga to 6502 based Centiped, to 6809 Based Super Pac Man to 8080 based Space Invaders.  Some players have complained about delayed reactions to inputs, software upgrades were implemented by the makers to fix this but complaints still exist.


GAMMA 1

The GAMMA 1 board was available for a short time with Pac-Man software installed.  It appears to be the same board as the JAMMA Multi-Williams board.

Bootleg Power Supply Adapter

Made by Greenbriar Marketing Intl (602) 948 0005.  Marked as "Li'l Green Giant".  This adapter is designed to plug into an original Pac-Man wiring harness and convert the AC voltage to DC voltages.  The board has provisions for -5 VDC (7095), +12 VDC (7812) and +5 VDC (LM323K).  The particular unit show above was customized to adapt an original Pac-Man harness to a PAC-3 bootleg Pac-Man board.

BOOTLEG MS PAC AUXILIARY BOARDS

Being that Pac-Man and it's spawn were such a popular item they garnered some of the highest flattery of the industry and some seedy elements too.  The seedy elements being illegal production of boards that looked like & played just like Pac-Man but were not made by Midway.

Original Ms Pac Aux board


Original Ms Pac Aux Board

Original Ms Pac Aux boards contain 2 2532 EPROMS, 1 2532 EPROM & 4 PALs. The Z80 is moved from the main CPU onto the aux board.

ABC or EFG Aux board

The above board is a unathorized Ms Pac-Man auxiliary board.  It is similar to the original auxilary board in that it plugs into the Z80 socket at 6B viva a ribbion cable.  It is different in that it uses a single PAL chip & 3 2764 EPROMs to replace the ROM code found on the main PCB.  (NOTE, you must still replace 5E, 5F character/maze chips to finish the conversion BUT unlike the original Ms Pac-Man you do not need original roms or any roms row 6!).

I've seen 2 variations of software used on this particular board.  The EPROMs are marked "A", "B", "C" or "E", "F", "H" with the A-C ROMs being a normal Ms Pac-Man and the second set (E-H)  being Miss Pac Plus (see Alternate Mazes? for more on this).  The EPROM data is in a scrambled format (not straight forward addressing) in a attempt to thwart easy copying.  The placement of the Z80 varies according to the PAL chip used.

If PAL = 65S then Z80 is by B/F ROM.
If PAL = 64K then Z80 by A/E ROM.

A = $DB4A
B = $0554
C = $ADB3

E = $70BD
F = $F85C
H = $144F

 

2764 ROMs

This board is similar to the above series but has 3 TTL (?) chips and is marked 2764 ROMs in the foil pattern.  These ROMs do not seem to be scrambled format.

A = $ B315
B = $ADAC
C = $AB2D

I find both the ABC/EFG and 2764  boards above very handy for my troubleshooting, coupled with a known good ribbon cable I can insert these aux board into a broken Pac-Man board & know if I have a problem in the main ROM area (row 6 roms) or possibly a bad Z80.   This is esentially what the Two Bit Score tester is only with "enhanced" test software.

 

Sex Change


The above board is marked "Sex Change" on the back.  It has one 2532 EPROM and one 2716 EPROM plus a 7400 and 74LS138 in addition to the Z80.  This particular auxiliary board is designed to convert a Pac-Man pcb into a Ms Pac-Man but it requires new (bootleg) EPROMs for all of row 6 & row 5 ROMs on the Pac-Man board.

2nd Alternate Ms Pac-Man Aux board?

Thanks to Steven T for pointing this one out!

All screen shots were captured with the use of the MAME emulator (V.24) or AGE  and yes I do own all the original EPROMs used to create these images.
