Ok, now I've got my GTEK 7228 EPROM programmer running, and I'm able to program many common EPROMS. I suppose I can also program single-chip EPROM microcomputers like the 8748, 8749, 8751, etc. if I can figure out how to make my EPROM programmer think it's programming a regular EPROM. Does anyone happen to know how to build EPROM programming adaptors, or know of inexpensive commercial sources of same? Robert Kelley rjk@sequent.com

I once wired up one for the 8751; you could program only selected individual devices and you could never read back what was programmed. The unit from Logical Devices I used later was MUCH more convenient. Philip Munts N7AHL NRA Extremist, etc. University of Alaska, Fairbanks

The 8748 requires an extra pulse to latch some addresses, so unless your burner has that algorithm, you're out of luck there. The TMS7742 looks like a TMS2732A. And I think one of the cmos 8051 chip can do this. markz@ssc.uucp
