Patrick Regan, from Bell Labs, has sent in a 2M
jpg of
Ken and Dennis at the console of a PDP-11/20, around 1970.
That's neat! I've got a very good print of it here (that huge Epson
color inkjet printer we bought at work really does a good job with the
expensive "photo quality" paper in it), and will frame it and hang it
on the wall of my basement machine room in my home. However (and my
ignorance is showing now, I know) who is whom in the picture? From Carl Lowenstein <cdl(a)mpl.ucsd.edu> Fri Jan

In article by alejandro gonzalez:
But the tape image also contains bootstraps for two kinds of tape drives
in the first 100 blocks. Followed by 3 x 4000-block RK05 images. More
than this I don't remember offhand, but I do have the "Setting up Unix"
document on a bookshelf somewhere in another office.
Can anyone point me to instructions on getting the tape in: Ken_Wellsch_v6
up and running on Supnik's Simulator? I have been trying some things, and
when it gives me the '=' prompt, anything i type makes the program freeze.
I have been following these instructions, the problem comes up when I
get the '=' prompt. I type: "tmrk", it just freezes.
The 6th Ed installation instructions say: The tape contains 12100 512-byte
records followed by a single file mark. Have you made the tape image for
Bob Supnik's emulator to match this, and what configuration file are you
giving to the emulator? P.S You can use the RK05 disk image in
Distributions/research/Dennis_v6/v6root.gz, or the RL02 image in
Bootable_Images/v6_rl02_unknown.gz,
unless you really do want to install V6 from tape.
The number of people in the world who have actually installed V6 from
tape is probably pretty small. But I am one of them, for better or worse.

Me too :-) But I've long since forgotten the details...

The documentation that Warren gave me describes the memory management
scheme. It says that when the machine is first started, the memory
management unit is disabled -- anyone know how to enable it, and where the
segmentation registers are (I'm assuming they are in the 0160000-0177777
range somewhere)?

All,
Here is how to install 6th Edition from the tape image v6.tape.gz
in Distributions/research/Ken_Wellsch_v6, onto Bob Supnik's emulator 2.3d:
I found makesimtape.c in Trees/2.11BSD/usr/src/sys/pdpstand in the
PUPS Archive.

I'll check my PDP-11 manuals when I get home; if I have a spare one I'll
send it to you. What was the model again? An 11/70 or something?
