Nope, it's a 16c622. The eeprom stores the settings. One of the things
that is really nice is the keyboard connector is assignable, you can
reprogram the MEMKEY to change which pins are rows and columns in any
order and combination, so the cabling is easy. The eeprom also stores the
keys and typematic settings.
