If you want those to work, you have to stick to 6502 from MOS, everyone else might have made small changes to the mask or the process which caused some illegal opcodes to behave differently. Sure. OTOH the tests showed everything to work, except that one that was (supposedly) also capricious on the MOS 6502 and therefore safe to ignore. Therefore my guess is then that the non-reliably working chips are either partially broken or of a different type/manufacturer than those I initially tested upon receiving the batch. All of them, obviously, were labelled as the very same type of Rockwell 6502s. -- SD! - http://e4aws.silverdr.com/ Message was sent through the cbm-hackers mailing listReceived on 2017-11-15 12:02:47
