Does anyone have a MITS 1440 Calculator? I am looking for someone who
either has a non-working unit, or one that needs some sort of
attention, or someone who would be trusting enough to loan me and a
friend their working unit to carefully swap the ROM chips and see which
one is bad. I think the risk of damaging a good chip is low, but
paranoid attention will be made to avoid accidents. I have been told
that the input chip is OK, and the output chip is OK. The control chip
seems OK. Most likely the program ROM chip is bad, but it could
possibly be the registers or ALU. More likely the ALU than the
registers chip.If anyone is interested in this project, feel free to
drop me a line. See July 1973 Radio Electronics for more info.

I wrote about this in December, but I figured I'd just give the
gentleman's email address in case anyone is interested in this. I think he
wanted quite a bit of money for it, so be prepared to haggle a bit.

All this talk about HP 1000 F reminded me that I have one of these
beast that I need to get rid of.
Anybody got anything good to trade? (Wang equipment would take
precedence)(TRS-80 and CP/M machines are cool).

> I am looking for info on this very early (1979) laserprinter.
I should have docs. Will pull them out of storage and try to get
it scanned for you.
The earliest Imagen printers used this engine. It was a beast..
The display doesn't show "CPU UP" (my memory may vary)
so it's got some problem. Up to $15 now. Since you
made me look around, I noticed there's a google group
for this item.

Hi Brian,
I read your post back in 2006. You said you have the manuals for "200 in 1" and "75 in 1". Could you email me a copy of both manuals? I actually need the manual for "160 in 1", but maybe the two you got might work.
thanks,
Robert

Reposting due to the resounding lack of response and the
possibility that something went wrong with the list right
after I posted the original...
I can buy or trade but I would prefer to trade. I have a large
collection of S-100 cards and some other goodies to work a trade
with. If it has the CUTTER ROM, all the better. If not, I can
burn a 2708 (and I'll probably post a "Wanted: CUTTER ROM dump"
message).
Thanks,
Bill Sudbrink
PS... To engender some discussion, does anyone on the list have
an operating Processor Technology Subsystem B machine?

It would be nice to try to get this documentation and software archived, if it
can still be found. There were a couple of generations of workstations, including
the obscure AI workstation that supported Lisp and Smalltalk. A friend of mine
worked on the 32000 based system before moving down to the valley.
The development systems that had their own OS, then a port of Unix called Tnix.
And, all the DC300 based 405x software..
