The Advin U84 that I use will do all EPROMS, PALS, GALS, EPLD's, MACH, etc from the late 1970's up through the mid 1990's... it craps out when the 5V devices fell out of fashion, and 3.3V (and lower) became popular. The DAC's they used couldn't supply enough resolution on the supply pins. Their newer machines will do the same up through current devices, but I don't wish to shell out another $4K for the capability.

If you are going to worry about things at that level, then it is not just the memory devices, you'll be worrying about all the programmable parts such as PALs, GALs, and other eplds. Then you are really looking fort some exotic programmers. Ironically, I bought a standalone programmer many many moons ago to back up a set of 1702's that I was concerned about. A few months ago, while cleaning out the lab, I found a paper listing of the contents of said UVEPROMs. Not quite sure where the programmer went to. :) On Oct 23, 2010, at 9:42 AM, Magnus Danielson<[email protected]> wrote:
