    1227747 TBI Chip options currently available? AT28C64 anyone use them?

    Starting to gather all the stuff for my Flathead TBI build this winter and am wondering what chips would work in place of the EPROMs. I know the 27SF512 is one but my programmer doesn't have the module for it, and it's obsolete. I see AT28C64 are still available...any other device options you can suggest? I am planning on a ZIF socket as I am SURE there will be a lot of changes to get this to run correctly on the flathead.

    Cheers
