Anybody ever burn your own EPROM from a rom dump and
just put it in a socket of a cartridge?
I opened up a cart today to see a socketed ROM in there in only one of the 2 possible PCB
locations for chips.
I suspect 2 were used in some cartridges...not in the breakout game I opened today.
Anybody know what eprom types are pin compatible for these if any?
I bet it's a relatively ordinary pinout...probably the ROM version
of a 2716 or 2732. I believe those chips have part numbers like
"2316" and such, if memory serves. There were lots of mask ROMs that
were pin-compatible with EPROMs in that era, before one-time
programmable EPROMs (plain EPROMs but in plastic packages with no
erasure window) became cost-effective.
Are the numbers on your chip readable? If so, what are they?
