Anyone have a "chip" number (not a GM number)??
I was wondering if there was some kind of number on the actual PROM chip besides a GM number. I am wondering because my dad's friend works for some computer company that orders these kind of chips all the time, and he could get me the chip if I had a number. Anybody know? Any help would be greatly appreciated. Thanks.

Depending on what computer you have.. you are looking for these
86-89 (or 90..I Believe these are the years) takes a 27C128
90 or 91-92 takes a 27C256
Texas Inst., AMD, Intel, STS, Thompson all manafacture this chip.

Yes, these eproms can be reprogrammed with the "prom burner" like the Pocket Programmer.
And to clear eprom "types":
86-89 MAF TPI cars used the 27C128 28-DIP
90-92 SD TPI cars used the 27C256 28-DIP
The MAF cars can actually use a 27C256 eprom, but the bin has to put on the top half.
And BOTH MAF & SD can use the Atmel AT29C256 Flash Prom. You just write onto it as you would write onto a 27C256. In fact, you can read an AT29C256 as a 27C256 or a 27C128 - but to write you need to program it as an AT29C256.
