Thanks to Batronix, I was able to upgrade my programming suite to handle GAL programming. The Euro/Dollar exchange rate helped -- a bit. Since my universe has been PROM, EPROM, EEPROM over the past 30 years -- I am looking for the best source for GAL purchase (brand, price, and within N8VEM/S-100 designers planned component selections) for the parts drawer. Known Quantity breaks helpful. greg chicago
