right).)
No prize yet. Hint: it's a microprocessor, not a mini (it's not the
IM6100 or LSI 11).
I'd either punt for 68k or 32000.

Hmmm ... registers are numbered, and
it's SRC,DEST format ... I'd
guess ne of the later PDPs like a PDP-10 or PDP-11.

What about the General Instrument CP1600 ? ...

Yup, you got it too--Sridhar got it first, though. One of the
lesser-known early 16-bit MPUs (outside of the gaming community) that had a
great instruction set, but lousy implementation and marketing.
It'd be kind of interesting to compile a quiz of snippets of assembly from
a dozen or so MPUs and see how well we do. No cheating allowed.
Cheers,

That is a new computer for me. I don't see any information on it on
Bitsavers or the web.
Anybody care to post more information?

Well, Lowell Turner has a bit of incomplete information on the general
architecture:
http://www.nyx.net/~lturner/public_html/CP1600.html
And here's a primer on the instruction set:
http://spatula-city.org/~im14u2c/intv/intro_to_cp1600.txt
I have the original reference manual, BTW.
When you get into the 10-bit nonsense, you'll see what I mean by an "almost
great" implementation. The interesting thing is that the intelligent
peripheral chip that was part of this set became the Microchip PIC...
Cheers,
Chuck
