curt: the hx-20 in mess is missing the i/o mcu which handles display and stuff dump. Kevtris did dump this just a few months ago, but it was never added. check your mail. EDIT: I also have the hx-20 technical manual here which has all the schematics etc and explains how the mem mapping/io and the cassete-slot rom expander works (it pretends the rom is a cassette and 'plays' it linearly thru a shifter!)
