hey, resolved? staring at a charcoal grey 820-00875, no read at first (using ch341 and homemade ez flash style clip)
am about to try again, any advice?
I learned a while back to pwr on and then keep pwr button held down. Machine should power off, button still held down, read chip, usually works on newer ones, this case, ?

if i have to remove the chip, I can, buy I would rather avoid it.

Also, has anyone found a zif/test socket for the wide 25x64 type eeproms?

I have to solder them to breakout board then connect to programmer, much time wasted...
