caius sent me these partial schematics he made a while back but I forgot to post them.
They are very clear and hopefully will be of use to someone.

caius is back again with two dumps from Cosmo Gang The Puzzle.
These are tested and in GAL16V8 format. Also note that these are from the ROM board not the motherboard.
Thanks once again to caius
caius has now dumped the PAL chip from a PGM motherboard.
I know some people in the past were looking for this so hopefully it will help a few fix their board.
Thanks very much to caius again
caius has dumped a PAL chip from Bucky O’Hare.
As usual with submissions from caius it is tested and already in GAL16V8 format.
Great game this one and thanks very much to caius for dumping this chip.
caius has sent in this dump. It is in GAL16V8 format and is tested.
There is a note attached too:
PIN 15 is cut and pads of the PIN 14 and 15 are joined on solder side of the PCB, probably this is a factory fix.
Thanks again to caius
