Got an A2286 #Amiga Bridgeboard back online, with the exception of the dead NVRAM / clock chip. It's the rev with the DS1278. Did the battery hack but still get checksum failures. Now to figure out how to read/write to this thing... the CS\ is controlled by the big FE3010 chip... #amiga#retrocomputing
Fixed a SYM-1 today. Two bad gates, an intermittent socket, missing ROMs, broken traces, leaky electrolyte and a whacky oscillator that was ~2/3rds duty cycle. #6502 #ee#retrocomputing
