http://project-megs.blogspot.com/ ... shows Parker Bros Wild Fire with a TMS1400! I picked up another one recently and it has an AMI S2152 like the first one I got. The first one didn't work and I wasn't able to dump it, but this one works so I'll try to dump it again.
I inverted the SYNC output with a 4049 and connected it to the ROMS input, and the chip dumps the first 1K of ROM bytes (but nibble-swapped: outputs D7-D4 are ROM data bits D3-D0 and outputs D3-D0 are ROM data bits D7-D4). I haven't figured out how to dump the other 1/2K yet. The first 1K is identical to the ROM image in the patent.
