And of course it is in TUHS! Remember we have 32V and SIII. For example,
look into
TUHS/Other/Distributions/Plexis_Sys3/
or
TUHS/PDP-11/Distributions/usdl/SysIII/
The sources contain 'bs' under cmd/bs
The latter one (under USDL) contains also the man page under usr/src/man/man1
(as 'bs.1').
So, there. You have it.
This leads me to consider we would greatly benefit from an expanded and
indexed TUHS repository tree. I made one on my mirror long ago, but a
series of disk crashes ended with it. Maybe, if there is interest I
could do it again.

Dear all,
(This has got to be the strangest cross-post I've ever done.)
I have just taken a bet from a friend to challenge my geekiness. I was
telling him about my love of Vintage Technology and he proposed that I
combine two hitherto separate hobbies and see what happens. The
topics: the DEC PDP-11 minicomputer (vintage: 1970s) and vacuum-tube
ham radios (vintage: 1960s). I do sincerely apologize for
cross-posting, but I am rather younger than either of these
technologies (vintage: 1984) and this seems like a monumental
challenge.
My question for y'all: how could I possibly design+build a project
that uses both of these technologies? My thought is to port some radio
receiver Digital Signal Processing (DSP) application into PDP-11
assembler, compile and run it via emulator on my PC, then use it with
the vacuum-tube regenerative receiver that I built a few years ago...
Does anybody know if PDP-11 UNIXes even had the capability for a
"sound card"? Or, to get ambitious, I would LOVE to design some
interface circuitry between PDP-11 digital circuitry and vacuum-tube
electronics... The challenges are legion: the tube side of the circuit
operates around 350V DC levels with radio-frequency (RF) signals at 7
MHz (almost the clock rate of some PDP-11s!) and I don't have the DEC
Handbooks, but I'm pretty sure that even those ancient pre-TTL
circuits operate below 350V!
So... any, er, "ideas"?
Best regards,
Ross Tucker
Hey there,
I have two questions. First, does anyone have the original files from
the Seventh Edition boot tape? Second, does simh support tape
operations like writing file markers? No doubt you can see where I'm
headed with this. I want to attach the original boot tape and install
the original V7 tape onto simh.
Thanks,
Brantley Coile
I was bored, and ported my version of SimH (which is an older
version, but with some stuff ripped out, and other stuff put
in) to my operating system for my ARM-based MCU board. It
now "acts" like a regular 11/83 when turned on, and will
happily boot Ultrix-11 off the CF card :)
Not as fast as running on a peecee, not half as much fun as
running a real '11, but hey, it DOES fit into my backpack.

Well, several projects can be thought off in this scenario, but
if you want to keep it mildly useful, try to do something with
audio tubes connected to an '11 (OK, here's a spoiler: "you'll
make a PDP11-driven music player using a tube-based audio
backend"), or such. You could go into analog computing as
well, but that can be kinda hairy.
This more or less only requires building a usable D/A converter
on the '11, which then interfaces to the tubes. I'd use a DMA-
based 16-bit DA controller.
Cheers,
Fred (smiling @ his nano-11 system running Ultrix, all the size of
a matchbox..)
Back in the 1970's Paul Pierce used a D/A converter on a PDP-11 at the UW
Computer Systems Lab to generate music much like early PC sound cards did
-- by combining harmonics in various ratios. Although he happened to have
used RT-11, there is no reason why it could not be done under Unix. (The
UW Computer Systems Lab also had a Votrax).
So, sure, you could, with an A/D and D/A converter do something like
that. I am not sure that the various emulators have done emulation for A/D
or D/A, but in principle, it ought to be possible.
AC coupling (via a capacitor) of the input or output would remove any
concerns about the relatively high DC voltages. Besides, input signals
ordinarily come into the grids of vacuum tube circuits by way of a
transformer. Ditto for outputs from tube circuits.

Sorry, this is a bit off-topic, but I'm not sure of anywhere better to
ask.
I used to have a number of HLH Orion machines, which were superminis
(they ran BSD 4.2 / 4.3) made in the UK in the 80s and very early
90s. A friend of mine still has some, which I suspect may be the last
ones extant, and a mass of documentation & media for them. He's
retiring soon and needs to find homes for them.
I think they're historically reasonably interesting machines - I
suspect they may have been almost the last significant British
computer design, and the earlier model was quite an interesting
machine, with user-programmable microcode &c (the later model was, I
think, not so interesting, if a lot faster).
Does anyone know of any museum-type places which might be able to
offer them a home? They are still working (we think, he needs to turn
them on). I'm thinking of approaching the Bletchley Park people, but
I'm wondering if anyone here has any better leads.
Thanks!

Hi all
the v7 rl02 dsk from archive , seems to be missing the /usr/sys , any ideas on how to restore it ? ,
also in the v7 as man page , there's reference to “unix assembler manual” by DMR , which I tried to locate without luck , the only thing available is the assembler reference manual , in v7 manual volume 2 , is it by any chance same documents under different name ? .
thanks in advance for the help

About one year ago I found installation tapes for System III for the VAX
somewhere on the Net. Unfortunately I can't find the original URL on disk
any longer, neither on my bookmarks and a Google search does not find
anything now.
The distribution is available as tap archives, and you can find it on
ftp://ftp.es.embnet.org/pub/misc/os/UNIX/sysIII
As four files.
My questions are:
- as this is the only copy I can find now on the Net, would it
make sense to save it also on TUHS and mirrors?
- the tap tools do not seem to recognize contents (dtp seems to
identify the first file) and I am currently too busy to further investigate.
Could someone with spare time have a look at them?
- a strings of tape1/set1 seems to reveal that it only supports
an RP06 at NEXUS 8 and a TE16 at NEXUS 9. Could someone with more time
have a try at them using SIMH?
Thanks.
