The number of people who come here asking for help, who apparently don't know
how to do a Web search, is pretty astounding. Get off my lawn.

Actually, I didn't write that; another CHWiki contributor imported it from
the Web. (Wouldn't touch SIMH myself... :-)
Most of the other pages at the bottom, in the 'See also' section, I did
write. Some of them might actually be useful. Also, at the bottom of the
'Installing UNIX Sixth Edition on Ersatz-11' page, there are links to a
couple of external pages that have lots of info on how to upgrade a V6
into something semi-usable.

Hello there I’m Resun a teenaged programmer who knows nothing about past days.
Here Index of /Archive/Distributions/Research/Dennis_v6 (tuhs.org)<https://www.tuhs.org/Archive/Distributions/Research/Dennis_v6/> there are some compressed file of v6 Unix.
And here’s SETTING UP UNIX - Sixth Edition (tuhs.org)<https://www.tuhs.org/Archive/Distributions/Research/Documentation/v6_setup.…> a documentation about how to set it up.
But the documentation is not for me I mean I don’t understand what it’s saying. There are terms like “Mount magtape on drive 0 at load point”, “Mount formatted disk pack on drive 0.”, “Key in and execute at 100000” and lots of other stuffs that newbies like me don’t understand. Is there any easy documentation about it? Or any documentation that tells us what does those terms mean?
Please help me.
Thanks.

This video got passed around at my (new!) job, and I think it's very
relevant to this list. It's Bill Joy talking about what he and Sun were
thinking about as the future of workstations and computing in general ca
1987. Some of the predictions were not accurate, but some were.
I'm curious what others think. https://www.youtube.com/watch?v=k8Pd6xYaHGU

hello there I'm Resun, a teenaged programmer and I love C and UNIX.
I want to use the 5th edition UNIX operating system. From here Index of /Archive/Distributions/Research/Dennis_v5 (tuhs.org)<https://www.tuhs.org/Archive/Distributions/Research/Dennis_v5/> I've got a compressed file of the 5th edition UNIX. I want to use it using the SimH emulator but there's no guide about how to install it or use it. I'm using SimH in Windows 10.
Can someone please help me to use this system?
Thanks.
I never saw his 32V work, but I reimplemented his additive random number generator in my own work.
Not too many people can write a 35 page PhD thesis.
Fewer can do it for Knuth.

As an offshoot of looking more closely at 32V, SysIII and 8th Edition I got interested in how each managed memory.
I’ve not deep-dived into the code yet, but from cursory inspection and searching past posts on this list, I get to the following summary:
- As has been documented widely, 32V essentially retained the V7 swapping architecture, merely increasing the maximum process size a bit versus the PDP-11 version.
- SysIII appears to have retained this, just cleaning up the source code a bit. I assume that all the V7/SysIII derivatives of the early 80’s were swapping systems.
- John Reiser further developed 32V memory management into a (reportedly elegant) demand paging system in 1980-1981, but this code appears lost.
- 3BSD/4BSD/4.1BSD developed 32V memory management into a full demand paging setup as well. This code base was dominant in the 1980-1985 era.
- 8th Edition pulled in the BSD VM code and is essentially identical to that in 4.1BSD. This choice was made because it was not a research interest and using a maintained code base freed up scarce time.
- SysV R1 appears to have retained the SysIII memory system.
- SysV R2 (floating about on the net, eg. here https://github.com/ryanwoodsmall/oldsysv) seems to have used a new implementation.
Questions:
Is that about correct, or am I missing major elements?
Several places mention that there was also a setup that was still swapping in nature, but did not require allocations in core to be contiguous (“scatter paging”). Did this get used much in the era?
At first glance, the SysV R2 code seems shorter and cleaner than the early BSD code (~2000 vs. ~3000 sloc). Is this implementation perhaps a derivative of John Reiser’s work?

- A machine description for the VAX that matches with that paper is for instance in the SysIII source: https://www.tuhs.org/cgi-bin/utree.pl?file=SysIII/usr/src/cmd/cc/vax/pcc/ta… <https://www.tuhs.org/cgi-bin/utree.pl?file=SysIII/usr/src/cmd/cc/vax/pcc/ta…>
- The new style description in 8th edition is here: https://www.tuhs.org/cgi-bin/utree.pl?file=V8/usr/src/cmd/ccom/vax/stin <https://www.tuhs.org/cgi-bin/utree.pl?file=V8/usr/src/cmd/ccom/vax/stin>
- The program that translates the “stin” file to a “table.c” file is here: https://www.tuhs.org/cgi-bin/utree.pl?file=V8/usr/src/cmd/ccom/common/sty.y <https://www.tuhs.org/cgi-bin/utree.pl?file=V8/usr/src/cmd/ccom/common/sty.y>

Sometimes one thing leads to another.
Following the recent mention of some retro-brew 68K single board systems, I decided to build a CB030 board (in progress). I figure it is a rough proxy for a 1980 VAX and would allow for some experimentation with the 32V / SysIII / 8th edition code.
My first thought was to use the M68K compiler that is included with the Blit sources (see THUS Archive for this), as I had used that before to explore some of the Blit source. That compiler is LP32, not ILP32 - which may be a source of trouble. Just changing the SZINT parameter yielded some issues, so I started looking at the PCC source.
This source does not have a “table.c” in the well known format as described in the “A tour of the portable C compiler” paper. Instead it uses a file “stin” which appears to be in a more compact format and is translated into a “table.c” file by a new pre-processor ("sty.y”). Then looking at the VAX compilers for 8th and 10th edition, these too use this “stin” file.
All the other m68K compilers (based on pcc) that I found appear to derive from the V7/32V/SysIII lineage, not from the 8th edition lineage.
A quick google did not yield much background or documentation on the STY format.
Anybody on this list that can shed some light on the history of the STY table and on how to use it? Any surviving reports or memos that would be useful?
Many thanks in advance
Paul
