In any case, it is pretty clear that these ATF chips are working a lot better than the original GAL's I was using.
That in itself is a great finding that hopefully will benefit other hw builders for years to come.

(My 22V10 -10 at home are Lattice, I checked)

These are the 2 GAL's I have been using...

The top one works absolutely fine and is a genuine 7ns.

The bottom ones, basically overall don't work at all. If they do work, not a very long. These were 12ns/15ns type parts so obviously reprinted. Even so, 15ns parts are the ones I am using now (ATF) and work absolutely fine. They should be good up to 80MHz anyway. Even 25ns parts should be fine really. So I really don't know what the problem is with these chips. They just seem like really really bad tolerances or something. Can only really assume they are factory rejects or something. Or used chips which have been subject to a lot of abuse which has damaged then somehow.

9.5 hours running with the Atmel GAL :thumbup:

Now to test some more out... obviously its not really viable to test each GAL for literally all day, but as they seem good so far, will have to limit to a couple of hours each test..

Though each final booster will be tested all day anyway... might take a while...

Need to look at my monitor today, needs a re-cap somewhere I think as its acting poorly :(

Cool, well done.

And don't you think it's time to buy a monitor of a more manly shade of pink :D :shock: :P
If it ain't broke, test it to Destruction.

Great, looking forward to it!

That table looks suspicuously (this is probably a Dutchism) like the famous IKEA model. I've got two bolted together on top of each other, using it as a stand for my laster printer :)

Though having Atari hw sitting on it is ALWAYS better :lol:

Randomly scattered Gal chips?

Looks very similar to my desk

The ones on top of the floppy drive are tested working.. the ones on the keyboard are the likely iffy chips..
