I have a pair of 2732/2716 EPROMs that are in rather poor shape. I am currently debugging the embedded CPU board they were on which has seen some moisture and battery damage. Both chips dump with something resembling data on my Willem and I/O data 29B but they are so beat up that every dump is giving a different checksum or holes in the data and rarely does wiggling the chips in the TEXTOOL yield a better result. I can't tell if this is just still dirty pins, bitrot or the chips failing entirely. I currently have too many variables between my two programmers to compare dumps between them so I'm looking for someone to help dump the chips and verify that I'm getting clean reads. The code should be MCS-48 instructions throughout.
