Later, Tek developed a microprocessor development system that utilized
an LSI-11 core.
It was called the 8250.
--
8550 and 8560
It was an evolultion of the systems that started with the 8002
8550s have an 11/02 in them and ran an OS called DOS-50, which
I would REALLY like to find. The 8560s are UTEK machines starting
with 11/23s and 8" drives and evolving through 11/73s and 5" drives.
I have an 8560 with an 8" drive and would like to find the service
manual for it (I have the svc docs for the 5" version).
There is a fair amt of scanned documentation on the 8002->8560 up
now on bitsavers.
And dovetailing into Hans' comments, it is VERY difficult to find
the documentation and software for these systems, while the hardware
shows up at hamfests and on eBay frequently.

Hmm, perhaps you can put up a list of these really difficult to find
docs, you never know some of us might be sitting on them not knowing how
rare they are.
For example the comment a little while ago about seeing a "rare" PDP-9,
I see one very day at the collection so for me it is not such a rarity ;-)

This strikes me as a first rate idea!

I just passed one up in a scrap yard. It had a pod for the Mil-Std-1750
processor hanging off of it.

I
have a 11/23 and 8" drive in mine. Maybe I'll throw the /73 CPU card I
have around into it...

I have docs for my
machine, (OS manuals, development tools, ...) but no
service manual. :-(

Thats my problem too. The system is
complete instaled. But the file
system needs a "fsck". Somthing that is on a stand alone tools disk,
that I don't have... :-(

I did make a few mistakes and an omission in my posting about Tek's
computer history.
First off, the MDP products did start out with the 8002, but that
was through the acquisition of a company called (I believe) Millenium Systems.
The 8550 and 8560 (I miswrote it as 8260) did use LSI-11's. The 8550 I
think ran DOS-50 (I think it only had two 8" floppy drives), and
the 8560 was the one that ran UNIX, although I'm positive
the OS wasn't UTek. It was more an AT&T System-III variant (as
opposed to UTek, which had its roots in 4.2bsd). I can't
remember what they called it, but it wasn't UTek. I used
to have an 8560 with single Qume DT-8 floppy drive and the Micropolis
40MB 8" drive. Thing sounded like a small jet plane at takeoff when
the drive was spinning up. Gave it away a long time ago. Wish I hadn't.
There was a predecessor to the 6130 that ran UTek. It was called the 6205.
These were 32032-based machines. Much more powerful than the 6130.
They could be had with framebuffers for GUI. I think that they had very
early X-Windows servers that ran on them. The display processor I think
was based on a National 32016. Tek sold a BUNCH of these at a
company "fire sale" when the product was discontinued. They sold for
fractions of pennies on the dollar. A lot of local Teks or ex-Teks
might even still have some of these in their garages/attics/storage units.

I have a rather large collection of 6205 systems. They were classified
as bigboard or production systems
I probably have a dozen bigboard CPUs, maybe 8 IOP;s a couple 6205
boxes with frame buffer and
graphics units. I don't have the OS anymore and my maxstore XT1105 is
not in good shape.
I' will take offers on the stuff, either boards or systems. Mail me with
your wish list.

It was called TNIX, I got the

It's a Micropolis 1200-series drive, also used in the PERQ 2T1. I have
service information (_real_ service information) for the drive, and a
homebrew test box that plugs into the 34 pin header on the logic board.

I saw a system in 1975 that they brought to the University of Missouri,
Rolla,
with what must have been an 11/45 or 11/70 (anyway two bays of stuff with
a largeish 11 in it). The system was called a transient system
digitizer. It was
the precursor of a system that uses a special double ended cathode ray
tube
to essentially paint at sampling speeds a signal onto a silicon charged
array, then
digitally scan the results off with another beam from the other side of
the array.
This was a very fast sampling oscilliscope read by what essentially was an
integrated tv tube.
Anyway, it would capture the data, process it and make wonderful graphs
of the stuff.
All of this was moved and was installed and demoed by Tektronix, not dec.
Not idea of O/S, since this discussion is about Unix, but at least Tek had
experience with "embedded" computing before unix came out and they
could get it.
