Well, I now have 2 EPROM burners, because one was purchased for me and the other was donated to me(Haven't got the software for it yet, it is a Needham Eprom Burner((copyright 1988 by Alan W. Needham)) that uses an 8-bit ISA expansion slot and if anyone has a driver, I'd be grateful. ^^) via a school program with some 27C256, 27C512, 27C1024, and 27C2048 chips. At first I thought the 27C1024 and the 27C2048 would be the same as the 27C010 and the 27C020, respectively, but the 27C1024 and the 27C2048 are both 40-pin instead of 32 pin. Is there way to use these in NES chips like the 27C0X0? If so, may I have the scematic?

Curse you, evil RF shielding! CURSE YOU, I SAY!

Those might be 16-bit EPROMs or something else. They probably could work (look up the pinouts on google), but they won't fit on the cart very easily and you'd be better off getting some 8-bit ones.
