Ms.Pacman Twin. (Susilu, 1992/1993)


The Story (part I): Back then, when we're dealing with the Tehkan World Cup stuff, a big local fan pointed me to this rare Ms.Pacman machine that allow 2 players simultaneously. It was located far from home, so... One day I made a big trip to meet this rare arcade. Once arrived, the owner told me that this machine was sold to another country. Too bad...

The Story (part II): Some years later, I went in vacation to another country's beach. Walking through the boardwalk, I noticed a local arcade. Once there, I spent some time seeing the machines, and... Oh surprise! The damned machine WAS THERE!
I made everything to contact the new owner without luck. One year later, I tried again and finally got his phone number. He borrowed me the board for a couple of days. Unfortunatelly, I didn't carry my camera so no pictures from the board. :(


The PCB is a PacMan bootleg hardware, with a mini daughterboard (normal in mspacman boards) plugged in. Here the specs:


Conversion kit for pacman hardware.
--------------------------------------------------

Mini daughterboard 3"x 5.5" aprox.

In the upper-left corner is vertically printed "SUSILU" and "NMPT008", and across: "MOD REG 294535" and "INDUSTRIA ARGENTINA".

Viewing from the top you can find:

U5 U3 U1 U2 U4


U5: 74LS245N (20 pins), with a capacitor soldered from leg 10 to leg 20.

U3: Unknown 40 pins IC, scratched to avoid recognition. Seems to be a kind of protection device.

U1: 40 pins male connector, to plug the kit into Z80's mainboard place.

U2: NEC D780C (40 pins), Z80.

U4: TOSHIBA MM24512AP-20 (28 pins), 512 Kbit eeprom.


The main pacman pcb has only two 2716/2516 eproms (dumped). I dunno if necessary, but the rest 6 x 2732/2532 eproms were removed. The owner didn't allow me to dump the U4 (eeprom) because it was soldered. Hopefully some day...
