AFAIK, with /CE low the time it takes to get valid data is tOE, e.g. 50ns vs. 200ns in a -200 'C256 (not that it matters at 1MHz). Anyway, I've successfully used Jim's adapters (with wired-ANDs when necessary) in various different 6502 machines without issues and I love 'em. mike Message was sent through the cbm-hackers mailing listReceived on 2012-05-14 19:00:45
