Notes[edit]

There are three different part numbering schemes for this GAL set. The Fusemaps are identical for all three sets, it's just the speed ratings of the GALs that differ.
Part number format is: yy-yy-yxy-yyy. Just x will differ and indicates the following speed ratings:
x=5 -> 33MHz accelerator - U9 10ns, U10 15ns, U11 7ns, U12 15ns, U13 10ns, U14 7ns, U16 15ns, U17 15ns, U18 10ns
x=6 -> 40Mhz accelerator - U9 10ns, U10 10ns, U11 7ns, U12 10ns, U13 10ns, U14 7ns, U16 15ns, U17 10ns, U18 10ns
x=7 -> 50MHz accelerator - U9 10ns, U10 10ns, U11 7ns, U12 10ns, U13 10ns, U14 7ns, U16 7ns, U17 7ns, U18 7ns
