In re-reading my email, I noted that I used the wrong size for the
rom, I would like to see a 2732 or C64 device or EEprom equiv.
If only one Rom, it should be a C64, with a jumper to select the full
device or lower or upper half of the device... easer to find part.
Room for a 27C32 or 27C64 boot/monitor rom or EEprom equiv
