Tektronix had a Unix variant called uTek that ran on a number of
workstations that they produced in the 1980s - perhaps that's what
you're thinking of? These started out with Nat Semi processors, but
later production systems were 68Ks IIRC. Most of them ran uTek,. but
some also ran a SmallTalk-based system and were sold as AI boxes. As
you'd expect from Tektronix products, the graphics were superb for their
day. The uTek boxes ran the X Window system and had Tektronix' own
window manager.

Does anyone know anything about this? What I *think* it was was
something that ran on a logic analyser (?) made by Tektronix, which
had some kind of PDP-11 inside them. I suspect it was actually 7th
edition or something similar in rather light disguise. I came across
one of these in the early 80s but never used it, hence the vagueness
of my memory.

First off, isn't it true that both these chips are the same or similar?
A short conference paper on the Bellmac-32 caught my eye because it
mentioned the various data structures the Bellmac keeps in memory,
such as process and interrupt control blocks. I'v become interested in
self-virtualizing CPUs (one well-known example being the IBM System/370
and up, running VM) and I wondered if the data structures make the Bellmac-32
a good candidate for self-virtualization. They are not tied to particular
addresses and a supervisor could inspect and alter its caller's data.
I'm still trying to get my head around the theory. So the manuals would
be interesting, but details about actual implementations would be even
more interesting. Perhaps MERT is relevant to this discussion.
Thanks,

I am copying all I can from the unix archive and will burn it to cd
because I know how precious they are. But what I was thinking was v5,6,7 for
example. Take them and add USB support. Linux would be a good example from
which to draw from. Because it's Posix. Much more could be adde to /dev.

Has anyone thought of or tried to port the gcc to the old unixes? It
would have to be a very scaled down version. A C compiler that would work
with modern c89 or c99. Something to get a C compiler working that would
compile todays programs. The old C compilers can be kept for safekeeping as
they don't work much anymore.

Hi there !
Over december last year I had my first wonderful expierence with a
micro-pdp11 running Micro-RSX.
In actual fact I haven't tried much, only a complete reinstall of the
system(which was unecessary, because I've got backup tapes !).
But still an amazing moment.
What I wanted to ask is, in what manner would one transfer old
data/programs/source code from an old
hard-drive/tapes/floppy to more modern drives etc. I basically need to
transfer controller-programs over to x86( Everything works, I believe, but
old hardware is scares) where I want to connect a modern pdp11-interface
card.
Thanking you in advance

Has anyone ever made a UNIBUS or Qbus USB card?

here is a note from Dennis about the history of the documents
that I've just put up on bitsavers
--
The manual is the 1st edition, a scan of which has been available at
http://cm.bell-labs.com/cm/cs/who/dmr/1stEdman.html
in various forms (all renditions of the same scan) for a while.
However, the annotated OS and software scan is new to me This is
a medium-age version of the assembler system for the
PDP 11/20, and is apparently without an MMU. A good find!
There were subsequent assembler versions for the (DEC Special Systems)
11/20 with an MMU and then for a while for the 11/45;
the first C version would appear late summer of 1973.
Regards and thanks,
Dennis
I am running linux and I want to devote a partition to a good working
old version of linux v5,6, or 7. I have Bob's simulator and it works great.
The thing is when I boot v7_rk05_1145 or v7_rl02_1145 which is I believe
Dennis's donations I don't know how to log out of the system. I also want to
make a filesystem for unix and I don't know how to do that with a pdp-11
emulator. I want the source so it can be generated too.
