Gary, don't spread such vile rumours :-) James Slayden was correct, the Z88
has a Z80. (I have one right here in my backpack...) Clocked at around
3.5Mhz, as I recall. OZ is actually an "operating system", rather than a
control program, though I have a few ideas on how to write a bdos/bios
emulator for it to convert those calls to the equivalent OZ functions. (If
you'd be interested in such a thing, let me know.)

OZ is multitasking, handles memory banking and management, has a hierarchical
file system, named device drivers, as well as floating point and long integer
functions. There is a complete reference manual (several hundred pages.) I've
never tried UZI, but it could probably be made to work in a Z88 with lots of
memory (they have 1Meg cards now, and you can use two or maybe three of them
at once [and still run on 4 AA batteries :-)])
