Notes
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.
