Hello Henry,

Henry>          I need the pinout for a 27c010 eprom. I'm planning on putting
Henry> some of my own homebrew utilities on Super Snapshot V5.2 cartridge. As
Henry> some of you may know, SSS V5.2 is a 64K eprom (27c512) and has no room
Henry> left in it, so I want to put a 128K eprom in it's place. The reason I need
Henry> to know the pinout is for programming the 27c010. The eprom programmer
Henry> that I have now only supports upto 28 pins, so I need to make a adapter to
Henry> hold the 32 pin eprom. Any info would be appreciated!

OK! Here's the pinout for AM27c010:
