Anyone got the fuse maps for these? I really don't want to have to
work out the logic by hand.
I don't know that I have them with me, but I do at home, since I make
the cards.
If you can find 7.5ns parts, go with them. I don't have my manufacturing
notes with me, but at least one of the GALs needs to be faster than 15ns
(it's probably the 22V10).
My device files are on an Amiga and the Compaq laptop I use to burn parts.
I don't think I have a copy accessible to me from here.
It's more than just logic - the GALs also handle the AUTOCONFIG equations,
emulating a nybble-wide ROM.
