if he was looking for a bad chip and he was an EE why did he not use a logic probe it check the chips of just swap like chips most EE's and hobist have a few chips laying around or from another board or unit that would make more sence
if he was looking for a bad chip and he was an EE why did he not use a logic probe it check the chips of just swap like chips most EE's and hobist have a few chips laying around or from another board or unit that would make more sence I know, I looked at it again, and the date was early 1992. So maybe it would be worth his time if he had an ok printer, and maybe most EE's couldn't afford their own logic tester back then. Was he even out of school by then?
