GAL Programmers

[Craig Hart]

Hiya..

I'm looking for recommendations re GAL programmers- 16L8, 20V8, that sort of
thing, ie something fairly general purpose with a good cross-coverage of
common types of GALs. Any kits or PC based programmers out there?

I can burn virtually any EPROM, but GALs are another thing althogether.
Also, if anyone is aware of one that can "reverse engineer" a GAL by
sequencing all possible input conditions and reading the resultant outputs
to reverse-guess the internal strucute, I'd be VERY interested...

Ta,

Craig

No info on this myself but if you find anything I would like to know as well.

I built a reverse engineering card out of a 6821 based printer card in my
Apple //. I still have to improve the software so that it can automatically
handle most chips. Straight combinatorial chips are easy - registered ones
are much harder.
