You will need an EPROM copyier for that. ---------^^^^^^^^^^ a 4164 is not an EPROM, its a RAM chip. Unlike the original Apple ]['s, the ROM is an unmodified 2764. The old ]['s used 2316's, which most EPROM programmers didn' support. Not only that, you have to make sure that you get the right type of 2764. It has to have 40 pins, and should have a 21v burn in, not a 12.5 or somesuch. I forget exactly, but I can tell you this: Radio Shack started selling the right kind for uner $6.00 ( I think. I forget.) They're sorta expensive, but then, that's Radio Shack. :-( sean kamath -- UUCP: {decvax allegra ucbcad ucbvax hplabs ihnp4}!tektronix!reed!kamath CSNET: reed!kamath@Tektronix.CSNET || BITNET: reed!kamath@Berkeley.BITNET ARPA: tektronix!reed!kamath@Berkeleyreed!kamath@hplabs US Snail: 3934 SE Boise, Portland, OR 97202 (I hate 4 line .sigs!)
