(I have no sources for the version for which I have the dist, and no dists for the versions for which I have the sources... I guess I need to bite the bullet and compile V4.20 myself.

RE: [pups] Bringing up the fist C compiler

by Ian King

About a thousand years ago, I recall hand-building programs for 8-bit microprocessors (in what we'd call embedded systems today). In many cases, I was the "assembler", writing directly in machine code which was then either keyed in through front-panel switches or burned into a PROM.... -- Ian -----Original Message----- From: Johnny Billquist [mailto:bqt@update.uu.se] Sent: Thu 9/5/2002 5:05 AM To: Tim Bradshaw Cc: pups(a)minnie.tuhs.org Subject: Re: [pups] Bringing up the fist C compiler On Thu, 5 Sep 2002, Tim Bradshaw wrote: > * Johnny Billquist wrote: > > > How?

[...] Ah. Ok, now I understand what you're asking for. You want to know what the first C was written in, and what that compiler/assembler was written in/on, and so on... No, I'm just deducting. Since the reference posted said that TMG was the first higher level language implemented, it follows that it must have been written in a low level language, namely assembler. Admittedly, the PDP-7 TMG *could* have been written in some high level language on some other machine using some tool that made a PDP-7 executable, so your guess is as good as mine. But even though I cannot account for all steps, I can guarantee that at the end of the chain, you *will* find assembler. I guess my MACRO-11 implementation of C isn't good enough. :-) (Well, it ain't mine, it's the normal DECUS C, but I'm hacked some at it.)

Vax 3300 and Ultrix

by Peter Wrangell

Greetings, I am looking for a copy of Ultrix 4.5 preferably on TK70 tapes but any medium will do. I have a MicroVax 3300 that I would like to breath life into again. Unfortunately the version in the Archives is too old to be of use and it seems that there is no DSSI support in NetBSD. I would be willing to trade old computer parts in return(I have Old SGI, Dec PDP and and Sun Stuff). Any help would be appreciated. Thanks. -Peter pwrangell(a)bsdmercs.org

The 11/20 I have (built 29/1/71, SN 821) has just plain 'pdp11'. The lead time on getting the machine was about 6 months. I suspect that the /20 was added as other models were in the pipeline (/05,/45). For a picture, see http://www.psych.usyd.edu.au/pdp-11/11_20.html > Incidentally, the machine's handbook was a wonder. Indead it was The front cover is interesting, in that it shows a table top version of the 11/20. It was quite possible to run one just with paper tape and an ASR33 with the reader/punch option. There was a similar option for the pdp8/e. The only obvious change between the first and second edition handbooks was that the latter changed the last page from a picture of a young lady in front of a machine to a table of Unibus pin assignments.

[pups] PDP11/73, RD53, RX50... What are my options?

by Tobias Russell

Hi, I have a micro PDP11/73 equipped with an RD53, RX50 and a Cipher mag tape drive (untested). The machine currently boots into TSX (although I don't have usernames/passwords so no shell access). I'd like to get BSD2.11 onto the machine. What is going to be the best route? I assume that my chances of breaking through TSX security (so I can use kermit) are small, so is vtserver going to be the easiest method?

Re: [pups] PDP11/73, RD53, RX50... What are my options?

by norman＠nose.cs.utoronto.ca

Carl Lowenstein: I suppose the easiest break-in tool would be a floppy disk with a bootable RT11 on it. Or, if your goal is just to drain the machine's brain entirely and start over, which is likely the case if you want to put 2.11 on it: dig up the standalone disk diagnostic (is XXDP easily available somewhere these days?) and reformat the disk.

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
