I haven't done it in many years, but after you get the machine to boot into RT11 you can disable the TSX security stuff. Probably a file named "STARTF.COM" is the initial RT11 startup and it contains the command to chain to TSX. I suppose the easiest break-in tool would be a floppy disk with a bootable RT11 on it. carl -- carl lowenstein marine physical lab u.c. san diego clowenst(a)ucsd.edu

RE: [pups] PDP-9?

by Fred N. van Kempen

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.

[pups] Unix and PDP11/20 (was PDP-9?)

by John Holden

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 A hardware story'

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.

Mine's older than yours

by norman＠nose.cs.utoronto.ca

Larry McVoy: In response to old hardware... My first machine was an Okidata CPM machine which had a color (!) monitor and a built in printer. If someone had one of these, I'd like it just for old time's sake... 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. Norman Wilson Toronto ON

computer inventory for hardcore geeks (fwd)

All, 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. Warren ----- Forwarded message from Wendy Murphy ----- >From jendywo(a)yahoo.com Sat Aug 31 08:22:00 2002 Message-ID: <20020830222155.14119.qmail(a)web14907.mail.yahoo.com> Date: Fri, 30 Aug 2002 15:21:55 -0700 (PDT) From: Wendy Murphy <jendywo(a)yahoo.com> Subject: computer inventory for hardcore geeks To: clintw(a)colorado.cirrus.com, xds_sigma7(a)hotmail.com, eric(a)brouhaha.com, iking(a)microsoft.com, mcquiggi(a)sfu.ca, emu(a)ecubics.com, dworkin(a)village.org, russell283(a)attbi.com Cc: rob(a)witte-family.net, jjdellea(a)chisp.net, wkt(a)tuhs.org X-Spam-Status: No, hits=0.0 required=5.0 tests= version=2.01 Content-Length: 3539 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. ~ Wendy the technologically incorrigible ----- End of forwarded message from Wendy Murphy -----

Ultrix...

by Johnny Billquist

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.
