These files are the custom GAL set that is present on the Atari
Falcon. All five are included, four near the CPU (U62, U63, U67,
U68) and one near the DSP (U44).
U62, U63, U67, U68 are 16V8
U44 is 20v8
15ns GALs seem to work fine, unsure of the original speed (12ns?)
Also included is partially reverse engineered files, back to their
Boolean expressions for anyone wanting to know the timing/inside
working of the GALs.
Should program fine on any GAL programmer. I used a Maxon GAL
programmer on my Atari STE.
