The sysboot certainly can be floppy and the system can be broken down to
multiple floppy volumes for installation. I may also be possible to use a
vax to read the CDrom and cut a tape(9track or tk50) from that as well.
This of course is predicated on the cdrom.
The V6 and V7 binaries however already exist and are available, getting
one of them onto a 11/73 and written out as non-image files would help
greatly.

I've got some AUUG newsletters ... One of
them mentions
a `Heriot-Watt stripped down 7th Edition',
If this is the version I have, which not only came from HWU, but is
running on one of their old machines, it's fairly standard. It was
build for a 'small machine', meaning one without separate I&D space,
such as an 11/34 (mine's on an 11/23 with 128KW and RL02s). There
are some extra drivers to support RX02s and stuff, but I think these
are just well-known additions from sources such as Boston. There's a
makefile to configure and build for a small machine.
It's missing some of the larger pieces of software, such as troff (nroff
is there, and the troff source AFAIR) and Fortran, and the tty driver is
modified (bigger!), but most other things seem to be 'normal'.
I have the source on 800bpi magtape (pity my drive is only 1600bpi) and
also most of it on RL02, though the RL02s are a bit disorganised.

All,
I had an idea about bootstrapping images into PDP-11s, please shoot
it down! Ok, I don't know much about the -11 hardware, how hard would it
be to bootstrap as follows:
hand-toggle in a small bit of code, which
sucks in a bigger bootstrap over a serial line, which
then can pull in a disk image over the serial line & write to disk
Flaws: need different bootstraps for different disks
need different bootstraps for different serial hardware
how to deal with bad blocks?
very slooow
Other problems: 5th, 6th Edition came as RK05 images. We could probably
build images for different drives.
7th Edition did a mkfs during installation, but I don't know if
bad blocks were ever dealt with.
Anyway, this solution would allow a simple program + disk images to be
put on your nearby PC running Linux/whatever, so no tapes or tape drives
would be required.
I've used this method on another hardware platform to move disk images
in/out. It is slow, but it works.
