The H/Z-100's also ran CP/M-85. As some of you know it was a dual
processor machine (8085/8088). Served well as a transition machine for
those who had lots of CP/M applications and were moving into the then-new
MessDos world. I've got two low-profile models (Z-110's, the model series
refered by Jeff as 'separate monitor configuration') one plain-jane with
just dual floppies and 768K RAM and the other I hot-rodded with UCI's IBM
PC Emulator add-on hardware, NEC V20 CPU and a 30 MB RLL HDD. The UCI parts
made it pretty much XT-compatible but a very few s/w applications which had
not been written completely XT-generic would give problems. Still a 7.xx XT
MHz machine by most any standards though.
