Unix was _developed_ on the 11/20. The first versions (up to the
fourth or fifth edition or so) didn't require an MMU, and, therfore,
had no protection whatsoever.
Dennis... tell us the "All out?" story.. please.. :)

Early editions of Unix did run on a PDP11/20, written in assembly language.
There was a memory mapping option KS-11 that sat between the processor and
Unibus that mapped chunks of memory. It was a DEC special, and only about a
dozen were built. See http://cm.bell-labs.com/cm/cs/who/dmr/odd.html

Um? Who said Unix used an MMU in the beginning?
No, Unix never ran on a PDP-10. It was PDP-7 and then the PDP-11, and I
believe it was a PDP-11/20 at the beginning.

Well, my first computer was a Cardiac. I'm glad to say that I managed
to grab one from Classic Computing a few years ago, but I don't think
they have any left. If anyone knows of a source, I'd be interested to
hear about it; every now and then I mention Cardiac to someone who hasn't
heard of it, and they'd like to know where to get one.
I still think Cardiac should be a required tool in freshman programming
courses.

I just received this e-mail. I have no idea who Wendy is, but
perhaps the things she has stashed away may be of some interest to you.

In my quest to get the house clean so I can get out, I
decided to inventory the computer stuff. It's like
inventory by the technologically blind! I got just so
far before I got frustrated and gave up.
Pat and Rob took the sillyscope (with the intention of
selling it, I believe) and the RT, I think it was
called (to keep for my ex-).
Dworkin took the PDP-11/73. I asked him for $84
because that's what I need to keep Xcel from shutting
off my electricity, but he chose to give me a check
for $500, which I have not cashed and won't until he's
had the stuff long enough to ascertain that it works
and tell me so, or for two weeks, whichever comes
first.
That leaves:
(Note: sizes are eyeballed by someone with a lousy
eye)
IN THE GARAGE:
various cables, keyboards, mouses, plugs,
cabinets, broken TVs, VCRs, and a Laser disk player,
and miscellaneous hardware
a box about 1'x1.5'x2' with a 3.5" and a 5.25"
drive, and seven flat buttons with colored lights and
symbols, like turtles, rabbits, and lightning bolts.
an Alpha Micro 1000E
Raster Tech monitor
D-SCAN, an 8"x8"x1" board with 17 female cable
plugs in three rows labeled "In" "Out" and "CH", six
columns labeled "R G B H V C"
a 3'x3'x2' dec RXO2 and RLO2
exposure timer & power supply unit
Sharp electric typewriter, and another electric
typewriter up too high for me to read anything off it.
a couple of Apple II+s (Dad wants to keep one as
he has some information on a 5.25" floppy formatted
for that computer)
SCM152 dry copier
microfiche reader ?
Kennedy model 9300 tape drive
AlphaWrite documentation, and several 3-ring
binders of documentation I just didn't feel like
thumbing through for particulars right now (but can
later, if you like)
and the infamous 78 2'x2' floor tiles. (Dworkin
said he's seen them advertised for $9 apiece, new.
They're not quite in new condition, but that gives a
ballpark for what they ought to be worth)
I didn't check IN THE LOFT, because it's too high for
me to reach or see.
IN THE FURNACE ROOM: I saw
an Amdex 300A video monitor
NEC multisync 2A monitor
Raster Tech monitor
ADDS (?) monitor
and at least one other monitor with no words I
could identify
An okidata printer
an ALPS ALQ200 printer
an IBM selectric II typewriter
a Minolta fax 261
and a "stack" -- y'know, a computer, with two
3.5" and one 5.25" floppy drives and buttons that said
"turbo" and "reset", but no brand name I could make
out.
IN THE CAVE: there remains
a Scientific Atlanta receiver
IBM monitor
IBM 3.5" floppy drive
HP LaserJet printer
Smith-Corona electric typewriter
Data south DS 150 printer
Microscience International Corporation thing that
says it has 7 heads and 855 cylinders, but won't tell
me what it uses them for
digital h3350; I don't know what it is, but it's
the size of a deck of cards
a couple of EMLock security door thingies
(magnetic)
various boards (green things with solder and
little batteries and stuff on them)
a couple of Alpha Micro video cassettes
That's what I had the energy to see. Can you
enlighten me as to what these things are and what
ought to be done with them? I can't even get at the
other stuff in the furnace room/garage until some of
it gets moved.

I know you don't support it. :-)

Yes, and it's *that* problem I'm looking for a solution to.

harhan.org don't exist from where my dns is looking... :-/
Another machine I have access to managed to resolve ivan.harhan.org to
208.221.139.1, but there is no response at that address.
However, if it is just the sources, and not some legal notes available,
then I don't need to go there.

I don't support NetBSD, but Ultrix' MSCP/SCA code is available to everyone.

It is a problem only if you choose to honor copyright laws. Since that is your
personal voluntary choice, it is your problem.

The International Free Computing Task Force has freed the Ultrix-32 V2.00 and
V4.20 sources. They can be found on our FTP site in
ivan.Harhan.ORG:/pub/UNIX/thirdparty/Ultrix-32

Hi. I have a small question for you.
I'm trying to figure out a way of getting the MSCP driver from Ultrix
available for porting to NetBSD.
The problem is that it's (c) by Digital, now HP.
Does anyone know of any persons who were involved in the old days when
code was exchanged between BSD and Ultrix? Those people might be a good
starting point for getting code today as well I suspect.
Does anyone else around here have any good clues on this?
Could I be lucky enough that Ultrix actually have been released?
And I'm talking Ultrix-32 here, not Ultrix-11.

Hi Joe, I've passed the e-mail on to some mailing lists, and hopefully
