I just got back from Japan, where NEC is selling a similar device for $600. It has a
keyboard that looks better than the EPSON kbd (and includes cursor motion keys, for them
what likes them), a 40x4 (320x64 pixel) display. The machine I saw also had katakana
characters available...
It was in a display case in a department store, so I couldn't test it out or find out
about the memory. It's a Z80, though.
