Okay...trying to burn a chip with chips I got in from China since they charge an arm & a leg stateside.
Chip reads as "Blank", enter a file then burn it to the device (M27C4002)
All seems well...here's the problem...>>>
When I do a re-read, the Checksum:xxxx xxxx comes up different every time.
Prognosis: Bad chip?
What do you think?
GX-4X USB ProgrammerST M27C4002-12F1 Singapore chips
Solved...was just oxidized device adapter pin legs...sprayed some CRC QD Electronic Cleaner on the legs...reads perfectly.
