Dave...Bad Chips!...these were "new" chips I bought back in 2012 when I joined this forum. I have (2) strips of 27SF512 proms...one that I marked "Chinese" and the other without marking to indicate US based. The US chips work fine...the proms marked Chinese are the ones not working.
Can you suggest a source for quality proms?
Even tried them in my MiniPro...
Thanks
Ed
