To do
Random notes I'm taking while dumping EPROMs. Will be a proper article in the future.
Common EPROM types
27C1000/27C1001
There are two types of 128KB/1Mbit EPROMs — 27C1001 and the non-JEDEC compliant 27C1000. Their pinouts have the A16 and output enable pins switched. An adapter/jumper wire is needed on some EPROM dumpers. The switched pins are marked red in the pinout pictures below.
