Hi guys, I have a need to program a number of M27C256B Eproms and have spent some time searching old posts to work out what I should purchase. At this stage I don't envisage doing much else with it, just this particular eprom . and probably only a few a month. I need to be able to copy a master chip, then reprogram several others with the updated software. Does anyone have any advice on the best device for the job please?
