npub13levfmuj9uu5gy4mhh0tg5nkujqujkyky8220rd0dkwpm4p950eqss6saf (npub13le…6saf) I did a bit of manual logic derivation/optimization last night, see https://github.com/michaelengel/lisaprom
If I didn't miss an optimization opportunity, bit 7 requires 19 terms, so it won't fit as it is. I think it should be possible to split the terms into two halves (one for addr bit 7=0 and the other for bit 7=1) and route one of the results back to an additional input pin. This would imply a longer latency for bit 7, but I think the GAL is fast enough. Need to give this some more thought...
