This is enough to get the ROM to boot into the PostScript
executive.

To handle the overlap with the SCC and the every-other-byte, make eeprom_r/w 8-bit wide handlers and add .umask16(0xff00) or (0x00ff). Check the SCC entries in mac128.cpp for a similar mapping.

ETA: just to clarify, it's legal to have two entries in an address map for the same space if they have different umask16s. The core will do the right thing.
