I am having problems programming my STM27C800 eproms. I am getting the right voltage on pin 32(12.5V)
I am using the same 16-bit adaptor as for my AM27C400 eproms.
I have noticed it takes like hours to erase the STM27C800 eproms.
Does it usually take hours to fully erase these STM27C800 eproms?
Also, am I supposed to use the supplied address cable? I did try that too.

Thanks in advance!

STM27C800 should use UV eraser to erase. Not the programmer.
