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? :-)

"Fortunately for Ward, by 1980 the community of computer researchers had grown from a few labs to a few dozen---and for the most part, the research community was moving in one particular direction: UNIX, the castrated Multics operating system that had been spawned from Bell Labs. UNIX was loved because it was small and portable, which meant that it would be easy for Ward to get the operating system running on the NuMachine. The group got the UNIX source code from Bell Labs and ported the operating system to three different microprocessors: the Zilog Z8000, the Intel 8086, and the Motorola 68000. Although it would not be clear for several years, by building a single-user computer with a bitmapped display, a network interface, and a powerful microprocessor, Ward's group had just created one of the world's first UNIX workstations.
