Pardon if you've heard this before, but...
I'm looking for the programming algorithm for Lattice/AMD/Cypress old
PALCE devices. I've got a bucketload of them (mostly PLCC) and I'd
like to do something with them or trash them, if no luck in the
programming department.
I've been looking for the PALCE algorithms for ages, and found precisely
nothing... On the off-chance you do find them, I'd love a copy...
There is a DOS PALCE programming tool floating around for one of the old
Sunshine EPROM programmers, and I seem to recall there being
documentation included on what the various I/O ports did. If you wanted
a weekend project, I suppose you could reverse-engineer that...
I've found algorithms for the PEEL devices as well
as NS type plain
GALs, but nothing on the PALCEs.
Any chance you'd be willing to share the PEEL algorithms?
I think the GAL algorithms were also documented by Manfred Winterhoff as
part of the GALBlast project... unless you have other documentation I
don't know about? :)
Thanks,
Phil.
