Hi all, I have a Dual Power Willem Universal EPROM Programmer and im trying to program up some 27C32 eproms.
I got an eraser and have erased my proms.
When I try to program the proms this error comes up

Error at 0x000A0F Chip = 0xFF buffer = 0x6F

Any Ideas as to what I am doing wrong???
Any help will be greatly appreciated.

Thanks
Paul.

Yes I have checked the eproms if they are empty. I have erased 10 eproms and have tryed to program 8 of them and with all 8 I get the same error.
