NOT FULLY TESTED! I had tested this adapter board with a 29F800 and it was not working. However, I'm almost certain that I programmed the memory chip wrong. The adapter probably works. But use at your own risk! I will update this if/when I have a chance to test it again.

So far only tested with an 8Mb game on a 29F800 in a 32-pin socket, and found to work. It should work fine with a 29F160 since the only difference is one additional address pin.
This installs on the backside of a mask ROM. You must cut/isolate the /OE pin on the mask ROM and tie it to Vcc.

UNTESTED! But should work fine, since there's not much to it.
This is a small adapter for a 74LS139 that mounts on the backside of a MAD-1 decoder. Use it to connect multiple (max 4) PROMs to the MAD-1.
0.8mm thickness is preferred for easier soldering, but 1.6mm thickness is probably fine. …
