I'm in a mess (What's new?). I need to find the checksums on four PALs,
3 x PALCE 22V10 and 1 PAL18V8
/history
Trouble in a machine of mine (Industrial PC, isa bus) has been traced
to a PAL. The manufacturer sent a set of 4, and the thing wouldn't boot
at all :-(. Pull one and put back the old, and I can boot. So they sent
another 4, with exactly the same results :-(. The latter four have
checksums. There is some issue in the machine about sets of PALs, but
they obviously have things wrong.
The same problem with both sets makes me think they could all be wrong.
The machine is too elderly to freight over to them, and I need to
check my set of PALs against their checksums. `
/end history
This country seems to have nothing to do this in the hands of anyone I
know or can leverage for a favour. My eprom programmer is a PB10 (The
old isa bus job) in a very old pc kept for the purpose, and an old old
old picstart plus.
I'll build something if I have to. What do you suggest?
