Hello,
I had asked this question on the tuhs discord channel, no response yet so i
figured i would try here.
I'm working to get my pdp 11/34 and 11/45 running. I was curious what
versions of unix or bsd would work on the machines i have. I wanted to set
up the systems with a bunch of dumb terminals and show them off at a local
maker fair.
If possible too, id like to be able to telnet in to unix or bsd.I was also
curious if a ethernet interface exists for my unibus systems, or if i could
SLIP/PPP serial to another machine,so i could telnet in as well as use dumb
terminals.
On a bit of a side question, did minix exist for the pdp11? There is
mention of it on wikipedia, but ive not found much other mention of it. I
read the minix book, and have used it quite a bit on the ibm pc, so i
figured i would ask if a copy for the pdp 11 is out there.

7th Edition Unix would run on either machine, and will support multiple
serial terminals. BSD 2.11 needs split I/D space, which the 11/34
doesn't have.

7th Edition has no Ethernet/TCP/IP capability. BSD 2.11 does.

Thank you for the valuable information.
It seems like v7 unix will be the way to go. Perhaps i can get some uucp
connection going over a serial line out of the machine, that could be
interesting.
I found this page, and it confirms what you said about 2.11 bsd, not
compatible with the 11/34 cpu.
https://minnie.tuhs.org/PUPS/node6.html
On the same page, there is mention of 2.9 bsd, and the 11/34 is listed as
compatible. Is tcpip availible in this version?
Thank you again for the helpful info.

No. 2.9BSD does not have TCP/IP. At least the distributions on TUHS don't
have it. 2.10 is the first one I can find with TCP/IP.
Ultrix 3.1 does have TCP, but it's not the most stable system when you
use it. It's kinda sorta 2.9BSD with some of the networking bits glued in.

A UNIBUS Ethernet interface does exist - the DEUNA. It is two boards,
and very power hungry. I have a a couple of third party Ethernet
boards from a VAX, but no documentation on them. They are not in my
inventory (they came from a couple of Intergraph VAX systems, and I
didn't inventory any of those boards), so I'd have to hunt to find them.
I doubt very much they are standard DEC software compatible.

IIRC, the DEUNA pulls 18 Amps from 5V.
But there was also a single hex board UNIBUS Ethernet interface from DEC,
the DELUA (M7521-AA IIRC, too lazy to look up). It uses a 68010 at 10 MHz.

A fully-populated 18-bit address space on the /34 and /45 is only 128K words, which seems
like a pretty tight fit for a TCP stack with practically sized buffers?
I had always sorta assumed DELUA/DEUNA were only practically useful for TCP on extended
Unibus machines (/70, /44, /24, etc.) but I could certainly be wrong on that assumption!

Certainly the 22 bit machines are a nicer choice, but various operating systems supported
DECnet on 18 bit machines, which is a similar size problem.
As for buffers, one data point is that the DECNA -- the Pro (CT bus) Ethernet adapter --
has on-board buffer memory. That memory is fixed at 64 kwords. And compared to typical
buffer allocations in DECnet (for RSTS anyway, the one I know) that's plenty large
enough.

There isn't enough memory and overlay space available for Ethernet
stuff in 2.9BSD.
