From an initial look at the the book however, it

address or substitute external ROM. There are some EPROM (68705,
windowed of course) and a couple of EEPROM (6805K2,3) variations.
Hmm, the 68705 is the EPROM family version of the 6805 family? I
wasn't aware of that. I have several 68705 chips kicking around and
haven't done anything with them yet.
