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 :-)]) _Mark_

Bzzzzzzztt, Sorry, no stove, no cigar. The Z88 uses a Z80. Sir Clive wanted the QL to have a Z80, but his engineers wanted the sporty 68008. With the Z88, he went back to the reliable Z80. The original poster was right in that respect. But the OS is not called OZ, it is called PipeDream. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Tim Swenson Newsletter Editor, Capital Area Timex/Sinclair User Group To respond in kind: "Bzzzzzzztt, Sorry, no stove, no cigar"... :-) PipeDream is the editor (a cross between WordStar and VisiCalc... I'm not kidding, ^PB for boldface, a number of other similarities...) OZ is the operating system and task manager. {Authority: I have the Z88 and the developers manual, and have written some assembly code on the beast.} _Mark_ <eichin@athena.mit.edu> <eichin@apollo.com>
