I'm really getting fed up with these EPROMs. I've wasted over an hour trying to get ONE more to program. I bought this batch from an eBay seller, along with some 27C322's. The 322's program fine, and previous 160's I have had programmed fine as well. But this batch I've only gotten three to successfully program. The others all fail program verify, or won't erase. I can program them full of zeroes no problem, then erase, and either they won't blank check, or they hit errors when programming afterwards - like there's some bad cells that revert or something.
So, does anyone have some good 27c160's?
Thanks!
