New subject: [pups] Making disk images and Ultrix-32
Two questions/observations.
The first is only tangentially on topic, but loosely related to
my recent attempts to revive Ultrix-11. Is there anywhere that
is, or is interested in, archiving versions of Ultrix-32 for the
VAX?? I would hate to see these become as scarce as Ultrix-11
was. We almost lost that one. I have numerous TK50's of Ultrix-32
software some of which actually loads.
Which brings me to my next and much more on topic question.
How does one go about creating a .dsk image from a real device??
Is it just a dd of the raw device or is there some software needed
to make the move?? And on a further note, if I made a .dsk of the
RA81 I currently have Ultrix-11 running from, are there any of the
emulators that would be able to use this?? If so, I would be glad
to clean it up and send it to Warren for the archive. (Assuming
I can use the Ultrix-32 system that shares these disks to make the
image.)
All the best.

Which emulator might I be able to test this out on?? Or do I need to
find something other than an RA81 to dump??

Yep, that works too!

What PDP-11 model do you have? Then I can tell you what emulators will
be suitable.
Thanks,
Warren

Is Ultrix-32 covered by the standard license from SCO? And did DEQ
release it to the world under the same conditions as Ultrix-11?
I think I have recent Ultrix-32 on CDROM here somewhere.

Ultrix-32 isn't covered by the SCO license (well, they didn't create it),
and we haven't obtained a release from DEC/Compaq, unlike Ultrix-11. So
while hidden away in the Archive are various versions of Ultrix-32, I
cannot make them available.
Does anybody have contacts inside Compaq so we could persue a release?
How does one go about creating a .dsk image from a

Use dd in single-user mode and dump it to a tape :-) That's all.
And on a further note, if I made a .dsk of the

To a tape?? What about just dumping it to a file on another disk??
