Gottlieb system 80b boot issues, rom links ?
The game is Bad Girls and it came without a cpu board. I have a spare possibly good board so I programmed up a 2764 from ROM1, however my stupid Willem knockoff will not program a 2732. I ended up doubling up the image and burning it to a 2764, copy/b image1.rom + image1.rom image1x2.rom, seemed to work fine.
Then I mounted the the chip with the 4 pins hanging out the top of the socket as per here http://the944.com/88_to_86.htm and tied 26,27 and 28 together.
Machine booted but said rom2 missing, found out it needed strapping differently so followed instructions here http://pinwiki.net/index.php?title=...no#Using_a_2732_game_PROM_in_a_System_80B_MPU
Now it will boot but seems to get stuck, no attract mode etc, but it will tell me if the slam switch and any of the tilt switches are closed/open.
Where do I go from here ?
