You're possibly right about ARM and CE, though. Several companies have
licenced the technology, but most of the ARM-based devices (eg the Psion 5,
Newton) use Psion's OS or JavaOS, not CE.

Are you guys both smoking the same stuff? CE does not exist for PA-RISC

hasn't shipped on any real hardware platform that I know of.
It has shipped on a couple of NEC MIPS derivatives and Hitachi SH. Most Windows CE devices are based on HP/NEC
PA-RISC (IIRC)
processors, or SGI MIPS processors.
Or Acorn/Digital StrongARM. There
is also support for ARM, PPC, and x86, but I haven't heard of any
hardware
shipping for those platforms.
ObCC-Q: What was the first microprocessor-based box to
run Unix?
ObCC-A: The Z8000-based Onyx C8002 in 1980.
What about the 11/23 systems Bell Labs were using in 1978?

Both :-) But given that it has a single chip implementation of the CPU
(commonly known as a microprocessor :-) I'd have to call it a micro...
Certainly my 11/83 is a micro/mini/as fast as an VAX-11/780 so I'm not sure
whether its a micro/mini/super-mini :-)

MIPS chips are MIPS chips. SGI own MIPS, but

and R5000 series.
Didn't SGI recently re-spinoff MIPS as an independent concern? In any
case, while the core ISA should be the same, NEC developed the VR4101 and
VR4102 specifically for CE, and I doubt that you'll find the chips in any
SGI box. I got invalid links when I tried to look at the specs at NEC's
site, but I think the CE-specifics were probably in areas of power
management and on-chip peripherals.
I also looked at HP's specs for their handhelds, and their marketdroids
simply listed "RISC" processor in an effort to hide the fact that their
not using their own processors, I suppose.
You're possibly right about ARM and CE, though.
Several companies have
licenced the technology, but most of the ARM-based devices (eg the Psion 5,
Newton) use Psion's OS or JavaOS, not CE.
It's public knowledge that Microsoft added ARM support for WinCE 2.1, but
that version of the OS is not shipping for any platform. In fact, 2.1 was
still beta last I checked (a couple of weeks ago).

I class that as a micro, but I don't know if
others would.
So, where do you draw the line? I draw it at one piece of silicon that
can stand alone with the usual support chips (ROM, RAM, glue chips).
