I chanced upon some old V7 stuff today, from a
researcher at the Duke University Medical Center
that did not have the heart to just throw them
out. There was a complete manual set for V7 from
a Perkin-Elmer NMR machine dating from 1984, and
a backup tape of the system (9 track Scotch 700
series 6250bpi) dated 12/17/80. The machine was
apparently an Interdata 3220 (Perkin-Elmer was
supposed to have bought out Interdata).
The manuals will make for fun reading, but there
may be some worthwhile bits if the tape is OK.
Anyway, I am seriously thinking of trying to
read the contents of the tape, and pass them on
to Warren, for the archives, if he thinks that
is something to do.
As to reading the tape, with the highest chance
for successful recovery, what would the list
folks recommend. I was thinking of just doing
a retension on the tape to wind it off the reel
and prevent sticking, and then maybe use the
copytape ditty that has been floating around the
net since time began, which should list file
sizes, block sizes, file types, etc., while
reading the files to disk.
I can roll the tape on a VAX or a Sparc system
using a Cipher M995S deck.
Any suggestions from the list?

I wanted to add the dz driver for multi-"terminal" support. But I'm
a bit stumped figuring out how to rebuild rl2unix, let alone how to add
the dz driver. (no rlconf/rl2conf file, although mkconf.c looks like maybe
it knows about the rl2 if not about the dz)
Is this do-able? Is the dz driver in the v7 image usable?

I think other things were updated as well, in line with differenet versions
of BSD, but I don't have any sort of definitive list.

To clone a disk, yes, you need to start with a good disk :-)

Linux source, especially early versions, or a full BSD 4.x distribution, eg
from the PUPS archive?

I've looked at the scripts (sorry, didn't have time yesterday). They're
not Acorn's. They were created by Granada Microcare's Field Service
division when they had to upgrade R140 versions of RISC iX -- 1.13 was a
They should work, providing the versions of the kernel and other files in
my version will fit on a floppy. I'm not sure how best to get your tar
file back though; it doesn't look like the minimal system has NFS support.
You ought be able to do it if you had a spare hard drive, put the tar file
on it, and mount it under /mnt. Modify the tar command in cpsys so it
doesn't overwrite /mnt, like James and I did.
dsplit is just a utility (written by Acorn?) to split a big file over
several floppies, or extract it again (like bsplit, but probably with

No. That's a linux invention. But I can probably create the floppies for
you, when I have time to move my R260 to somewhere I can use it -- probably
not this weekend, maybe the weekend after.
What machine have you got? R140, R260, or something else? Is it the same
type as the filesystem you copied came from?

I think NetBSD supports these machines. See

It is indeed a straight port of BSD 4.x, where x depends in whether is it's
RISC iX 1 or 1.2 (R440 used 4.2, I think; R260 used 4.3).

Take a look at James Carter's page at
James and I worked this out when we rescued half-a-dozen R260's in various
states of disrepair and with various not-quite-complete copies of RISC iX.

It is a standard 4.3 filesystem (at least for the verison for an R260). It
even says so when it boots:
RISC iX Release 1.2
ARM3 processor, cache enabled
Root fstype 4.3, name /dev/sd0a
Swap fstype spec, name /dev/sd0S
One of us could copy some stuff for you. I'm not sure you'd be able to get
what you need onto a single floppy, though. That's not how Acorn did it.
We'd certainly be willing to help, especially if you have any RISC iX stuff

now that i've signed up for this list I have forgotten what the topic is?
I am a disabled veteran, I do some work with Linux as a hobby, and some
web sites, also as

I found some ufs code in the HURD source, and VERY crudely hacked it. It
creates filesystems that linux can mount, but it crashed trying to write
big files to it (doh!)
any advice from the list would be appreciated :)
