Hi. I've got a batch (aprox 3.000) of AM29F010B-90JC devices (PLCC-32). 1Mb flash 5V-only (no Vpp) flash in 128 kbit x 8 layout. http://www. amd.com/us-en/FlashMemory/ Click "Flash memory", then "F Family", and then "F10B"... Now, from what I've read, there seems to be a "erase- disable" bit that can be set in these chips. And, if I understand right, if it *is* set, the devices are OTP (they *are* programmed). I don't have any prog equipment myself to run an "erase-check" on them. If someone does have that, and would like to test a few, I'm offering a tube (about 30) of them in return for the service.
