According to Gordon Bell's "Computer Engineering", the primary differences
from the -4 to the -7 were switching from 6-bit to ASCII I/O devices and
the addition of a trap mechanism. The -9 primarily changed the memory
system, going to 2-1/2D core; it was also microcoded. The -15 went to
TTL ICs and added index registers and memory relocation. He says
"The PDP-9 instruction compatibility was acheived with three minor
exceptions about which no complaints were received", although I don't
see an explanation of the exceptions.

Hey gang,
Does anyone have an online manual or other info for the DQ686
ESDI disk controller from Dilog? I'm trying to fix a VAX 4,
which as that beastie...
Thanks,

There is a manual for the DQ696, which is essentially the same thing
except it controls 2 drives not 4. It was last seen by me at
< http://www.miim.com/documents/dilog/dq696.zip >.
It is zip-compressed MSWord.

we all know that UNIX first ran on the PDP-7 and then on the PDP-11/20,
but does anyone know anything about PDP-9 UNIX? it\'s mentioned in \"The
UNIX Time-Sharing System\" in the V7 manual:
\"The earliest [version of UNIX] (circa 1969-70) ran on the Digital
Equipment Corporation PDP-7 and -9 computers.\"

Hi all
Firstly, I have done this before, but due to age/stress/tiredness/whatever,
I can't remember what I did!
I am using Warren's/Fred's vtserver program to install BSD2.11 on an 11/53.
I have installed the root.dump file (and all the steps beforehand) and now
my '53 boots into 2.11. So far so good!
I now need to restore the usr file systems - all the stuff in file6/7/8.tar
How do I do this still using Vtserver.
Someone remind me please!
Regards
Kevin Murrell
You could also run Unix v6, if you're of a historical bent; 2.9BSD
should run with no problems; and possibly v7, if you have the 22-bit
address bus and enough RAM. Keep in mind that if there isn't a
distribution for your machine, you can build one on an emulator, then
create a disk image. However, with v6 I ran the 11/40 image on an 11/34
and was able to rebuild for my hardware.
Warren wrote a neat tool to get bits onto a machine over a serial line;
it takes a while (at 9600 baud!), but it works. Look on the PUPS site
under VTserver; don't worry that there probably isn't an installation
package for a given version or machine, there's a way to run a small
client on a PC that can talk to a bootstrap on the target machine. --

Ultrix-11 if you can get a 9-track tape drive. :-)

Either a small system like V7, or Ultrix-11.
And no, you don't need a tape drive... as long as you have a PC
around, and the PDP-11 has a serial port, you can use my VTserver
package to install Ultrix over the console port.
Cheers,
Fred
I've acquired a PDP-11/24 with 2 RL02s and a RA80. What are my options
for running Unix?

Hmm, but where is it? :-)
