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.
This is made to fit on the backside of a 32-pin PRG mask ROM, without having to remove the mask ROM (just clip /OE and tie it high).
If you use a 29F800, A19 is tied high so it will act as a 4Mbit ROM.
C1 is for an 0805 0.1µF capacitor.
