Hi, I know very little about electronics and eproms so this question might be really easy. I would like to know what the difference is between a 23512 eprom and a 27512 and if there are any differences if its possible to make some sort of adapter. Had a look at some schematics and they looked the same to me, data lines on the same pins etc. Any help is welcome. Ow the reason I want to know this is that I want to read some old roms in my EPROM reader. Cheers, Stefan.
