Need a MEMCAL

[EagleMark]

I'm a car guy that learned to use computers for cars.

That question is for a computer person. I have no idea what would happen to a UV erase chip if it were in a programmer and you tried to erase?

i've tried it before.... nothing happened as far as i know. i stuck a factory MEMCAL into the HDR1, put it in the BURN2, read off the BIN, tried erasing it as a 27SF512, read it back, i THINK the BIN was identical....

but if it were put in backwards and attempted to erase, that's a different scenario... certain pins will not tolerate certain scenarios and you'll burn out the little links that you can see in the quartz window with the sticker removed.

i just mention static since it's that time of year. you don't have to see or even feel the arc for it to be enough to damage a PROM.
