PENGO (Sega, 1982)

Pengo comes on a small single board, about 11"x12".

              PENGO - SEGA 1982

These roms are from my original Sega Pengo PCB.

The PCB is marked '834-0386' Rev. C, Serial 106922.

I understand that the roms are encrypted.

The rom layout and markings as per the eproms are as follows:

E                IC7              IC8
D                1690B            1689C

G                IC14             IC15
E                1692B            1691B

C                IC20             IC21
O                1694B            1693B
N
                 IC31             IC32
                 5119C            5118B



                 IC105            IC92
                 1640             1695

The music has the correct 'popcorn' tune.


[Jan/26/97]

The board from which these ROMs and PROMs were dumped
was a Sega original board, with no potted components.
CPU was a standard Z80. 

The only "catch" was PR1634 at IC88.  This was a NEC chip
marked "R8148IY/B426".  A look at the schematic showed it
to be a 1024x4 PROM, which matched the pinouts of a TI 
TBP21S41.  It was read in as a Signetics 82S137, a 21S41
cross-reference.

This is a game called Penia taken from an Italian Zaccaria cabinet.
It was either manufactured with this game or professionally converted.
It seems identical to Pengo by Sega (inc. pinout), and a friend tells me that 
the music is the elusive "Popcorn" music (though I personally have no idea 
what this is!)

The files are labeled by IC number followed by the device label, where present.
The 4K files are all NEC D2732D.
The 8K files are all Mitsubushi M5L2764K
003_PROM is a Signetics 82S153
051_PROM is a Texas Instruments TBP24S10N (read as a Signetics 82S123)
078_PROM is a Texas Instruments TBP24S10N (read as a Signetics 82S123)
070_PROM is a Texas Instruments TBP24S10N (read as a Signetics 82S123)

        This archive is of a Pacman PCB conversion. It is
        missing the intro screen with the ice-scape though.
        Probably to reduce the size of the software. It
        seems to have been done by David Spicer. Check
        ROM5A.6K :)
