Hi Guys,
I'm repairing is old Atari 800XL board which gives a RAM error. It has MT4264 ICs soldered in. I've done some web browsing and it seems to me that NEC 4164 ICs are compatible with these.
I've got some spare 4164s so I got brave and tried the piggybacking technique to see if I could identify the offending chip. Sure enough, when the 4164 is piggybacked over one of the 4264's the machine passes it's memory tests and boots. In fact, it seems ok?
Before I go and socket/solder this in though, I just want to check with knowledgable people that these are indeed 100% compatible.
Does anyone know if they are not?
