Does anyone know where I could find a distribution of BSD 2.9 that I could
install on my PDP-11/23. Also, will it work with just a 'TU58' (or
possibly two) - I should hopefully have a working emulator by the end of
the week - and 32kW of ram? I don't need it to do much - I'd just like to
have something set up to play with a little.
Thanks!

I've links on my page to PUPS, they're who host the UNIX distro's.

You're going to need more than a TU58 and 32Kw RAM. I don't remember how
much RAM, but, IIRC, you'll need at least 1-2 RL02 drives.

I've installed 2.9BSD onto a real (not emulated) PDP-11, an 11/24 w/1MB
of RAM, RL11, 2 x RL02 and a 9-track drive hung off of a Dilog tape
controller (this was long ago, long before PUPS).
My recollection is that the primary distro fits on a single RL02; you'll
need a second one for the source archives (to remake the kernel). It
runs in 256K, but that doesn't leave lots of RAM for user processes.
ISTR that I could run rogue, but not dungeon (an older version of
Bob Supnik's FORTRAN port, not 3.2A).
I bought a real KT24 and a couple extra megs of RAM (from Terry Kennedy,
about $500 c. 1988, ISTR) to run 2.9BSD comfortably. The real problem I
ran into was disk space. 4 RL02s just wasn't enough space to really have
fun. If I would've been willing to drop another grand, I could have had
a Unibus SMD disk controller and a decent sized (capacity, not weight)
SMD disk.
It's a good UNIX to play with. Completely recognizable by today's
standards.

New subject: PDP-8 available in NZ ?
I was forworded this email. If there is someone in the NZ area, you
might want to check this out. I have no association with this, so please
don't send me email about it...

Subject: PDP 8
Dear Sir.
I have a PDP 8 (circa 1965). Is there a market for such a museum piece?
Has it a value?
Sincerely

this is of course going to be a very limited system, but the memory requirements
for 2.9BSD are 192Kbytes of ram.
2.11BSD on the other hand requires 1MB ram and split I&D.
big difference there. ;)

That's why I stuck with 2.9BSD for so long... my first split I&D
machine was a Pro380 ex-VAX Console. I have only recently aquired
an 11/53 board from a DEC comm server (with real PDP ROMs installed
so as to act as expected). Since I _do_ have megs of Qbus RAM
and MSCP controllers, etc., I'll be using 2.11BSD with that.
I did solve my RL02 space problem in 1994 - I imaged my real magtapes
to disk files on my own SPARC1 (via a MicroVAX w/TU-80) and put up
a PDP-11 emulator and got it all running - ISTR it ran at about 30%
of the speed of the real hardware - on a 12MHz SPARC!

There's no way you're going to be able to run BSD 2.x with only 64kb of
RAM, you need about four times that! I'm not sure how much disk is
required, but it will be measured in megabytes, so TU58s won't be
sufficient.
5th or 6th edition would be more practical on this system, though you'd
probably have to write a TU58 driver.

I thought 5th & 6th were limited to Unibus systems.... For that matter,
will 7th even run on a Q-Bus system?

If you have under 256KB of memory, and only I/O devices equivalent
to the corresponding Unibus devices, it should be possible to get
them working. To software, an 11/23 with 256KB of memory is not that
much different than an 11/40 with KT11.
I remember hearing of someone running 6th edition on an 11/23, but I
don't recall who it was, or whether modifications were required.
