I've got a handfull of these things that I've been trying to use. My programmer supports them, and I was hoping that they would have the same pinout as a 2732. At the moment, I'm not so sure. So far, I've had three of these chips in the eraser for a good 45 minutes total. If I set the programmer to the ICT 27CX321, it won't blank check - although reading it in and examining the data produces something composed mostly FF's - though not entirely. If I set the programmer to a generic 2732, it passes blank check. I haven't tried programming one yet - although I suppose I could try to fill one with zeroes. So, I take it that these things have a different pinout? I can't find any data on these. Any help would be appreciated. -Ian
