1x JAMMA edge connector
1x 6 legs connector (conn1)
1x 15 legs connector (conn2)
1x 4 legs connector (conn4)
2x trimmer (volume)(p1,p2)
1x battery 3V
This is the same PCB revision (950510-1) as already documented in MAME source gaelco2.c, but with a number of differences:
1) Gaelco custom chip is 449 instead of 506
2) total EPROMs size is less than in revision 950510 (more specifically it looks like the content of 09,10,16,17 is missing)
The PCB is totally dead, therefore I can not make any screen comparison.
Comment from Haze: "it's very obviously missing 2MB total rom data, so something isn't dumped at the right size. (there are no empty positions, so it's clearly a 'wrong size' error)"
Comment from Brian Troha: "So if it’s missing 2MB of data, one of the mask roms IC70 or IC69 is dumped at half size."
Comment form me: "Unfortunately this PCB was bartered for something else a long time ago, it's no more available."
