I was poking around Google today and came across 4.3BSD Quasijarus as
something that might be interesting to try in SIMH and maybe on my
VAXstation, but the ftp site seems to be empty. Does anybody have a
mirror of the Quasijarus 0c distro? Without seeing the files, I don't
have any idea how it is distributed... I'm hoping it's a CD-ROM image
so I can install easily on my vaxstation--anybody know? And yes,
NetBSD is just too new for me :)
Thanks

Looks like a set of file that are decompressed and then written to a

In this case your only chance is:
Install from virtual tapes into a simh machine.
Use a virtual disk that matches your real one exactely.
Dump (dd(1)) the virtual disk to a file.
Boot NetBSD diskless on the VAX.
Dump the disk image from the simh machine to the real drive.
But instaling from real tape is much more fun. :-)
(I created the tapes by booting NetBSD on the VAX.)
You may have a look at http://www.tuhs.org/
There you will find the original 4.3BSD-Tahoe.

There's a standard readme which describes (with holes) now to install it
from tape. Basically you boot off the tape. I have
the tape image
somewhere. I think I also have a simh ra82 image of 0c. it's
20mb
compressed. It's in a directory with a simh config, so it might even
work :-) I can try if you like.
If you have the images it's easy to write a shell script to reconstruct
the tape image.
At one time I had his whole cvs tree. The machine it's on is at my
office and we just had a big snow storm, so it might be monday before I
can check. I would think others would have it also.
I'd be happy to host it on my web site. (but I'd think bitsavers would
also be a good place)

I haven't used Quasijarus on a 730, but lo these many
years ago, I did run 4.2BSD on one. I'm pretty sure we
were using a 750 by the time we moved to 4.3, but I
just looked at the 4.3 docs, and still see some reference
to the 730, so I'm pretty sure that the 730 was still
supported in the BSD release of 4.3, and I don't see
any reason to expect that would have broken in Quasijarus
since then.

No, but I have a, 11/725 in the corner I need to diskify and get working again.
I don't mean to bring up the "how crappy RC25s are" thread, but I
either need a cartridge (so I can spin up the internal drive, too), or
a workable Unibus disk solution (SCSI or SDI or ESDI - I doubt the

Also, I should check the memory in it - ISTR it's limited to 5MB.

Yes, the 725/730 is limited to 5Mb, although it's tricky to find enough
slots for this if you've got any peripherals. I have a 11/730 that's
fortunate to also have the BA11-K UNIBUS expander box, so I've got room for
5Mb, but that was an unusual configuration.
The memory boards used in the 730 are the same as the 11/750 1Mb memory
boards.
My 11/730 runs, except for the R80 which needs a new HDA (alas, Rx80 HDAs
are pretty much unobtainium today), however it also has a UDA50 and two
RA81s, so there's plenty of disk space. I'm afraid I'm not much interested
in Un*x, but I'll ask my wife (who is the Un*x dweeb) if she's interested in
trying Quasijarus/BSD on it.
Is there a 9-track distribution? How do you install it? Normally you'd
install VMS from 9-track by booting S/A BACKUP from TU58 or an RL02 pack - I
assume there's some kind of stand alone mtboot program for Un*x, but what
media do you load that from?
I've also got a 11/725 that's in good shape except for a few missing
pieces of sheet metal, but like Ethan I've no working RC25 drive. A UNIBUS
SMD controller is an option - there are some small 8" SMD disks that mist
just fit inside the chassis in place of the RC25 - but a UNIBUS SCSI
controller would be a better way to go, since it'd be no problem to fit a
SCSI disk in there. Unfortunately neither SMD nor SCSI UNIBUS controllers
are easy to come by.

5.25" SMD drives do exist; Seagate (and possibly others) made

Mine was also configured with an expander, but I only got the 730Z rack.
Along with that I got up to a total of 4 or 5 1MB boards, a TC13(?) tape

pick up a BA11, in case it's supported.

The reason I was able to acquire the machine as surplus in 1990 was that
the R80 was throwing bad blocks constantly, causing grief for the lone
researcher that was using it as a big, noisy PC for running her FORTRAN
code. I was able to connect her with another lab that had decommissioned
11/750s lying around with racks of RA81 drives they were willing to
provide via internal transfer.
In a fit of youthful idealism I pitched the entire R80 mechanism,
figuring that SCSI was the One True Path and the IDC was supposed to be
slow anyway. Well, and the fact that I had to find a nearly unused
circuit from another room just to spin the thing up... Pretty dumb to
toss it, but that's hindsight for ya.

Yes, I did it a few years ago and it worked fine for me. As I

[...] For that, our 11/730 with Ultrix 1.1 (4BSD covered in
DEC-hardware-specific scripts and other DECisms) with its 120MB R80
fit the bill better, even though the CPU was 75% as fast.
I recall that the only other 11/730 that I saw in service back in the
day was running Ultrix and serving as little more than a print spooler
for a line printer. Again this was ~1990 and the labs in question
weren't hit with an electric bill for running these things in a way that

Yeah... that would be a great question to have answered... from what I
recall from 20 years ago, there's 5 slots in a KA730 backplane wired
to work with memory, but only enough to refresh 5MB of 1MB cards. You
could stuff two 4MB cards in a late-model 11/750 with a newer memory
controller (plus six 1MB cards), but the 11/750 could *not* be
expanded more because it's VAX address space was limited to 24 bits of
RAM out of 32 bits total (16MB total address space, like an MC68000).
I haven't closely examined the KA730, but *if* one could fill the
entire address space below 8MB with RAM, one could theoreticaly make a
new-build 8MB single card for it, perhaps with a fresh address line
run to a memory slot. I would be surprised to hear that one could
exceed 1MB/slot in an unmodified KK730 backplane. These days, I'd
personally recommend sets-of-four SRAMs to make a 32-bit-wide
datapath, making 2MB trivial to put one one card, *if* the memory
slots would easily support that. I've run wires on a 256K-card
VAX/11-750 backplane. I don't mind finding a way to support 8MB in
one to four cards on an 11-730Z backplane, even if it necessitates
fresh backplane wires to pass along extra multiplexed address bits.
Encoders and decoders are plenty cheap compared to limited backplane
realestate.

Probably it is time now to make new memory boards for the vaxen and

Back to the original subject, yes, you install 4.3BSD Quasijarus by
booting the distribution tape.
I created my own 9-track tape by grabbing the distribution files from
the net and then writing them to a tape. (I used some DOS utility
programs I wrote along with a PCTD16 controller in a PC to write the
files to a tape.) I then booted the tape on a KA655 with an Emulex
QT13 controller in TMSCP mode attached to a Fujitsu M2444AC 9-track
tape drive and installed on an RA70 disk drive attached to a KDA50.
I basically followed along with the installation info I found here and
gettting a basic bootable system installed was fairly straight
forward.

Here's some other notes on the net that are 11/780 specific.
http://www.employees.org/~kirk/page0207.html
Looks like it involves loading some bootstrap images into the
simulator at various stages during the installation process with
simulator commands that I am not familiar with:
Example:
sim> load -o ./tp/copy 0
sim> run 2
sim> load -o ./tp/boot 0
sim> run 2
sim> load -o ./boot43 0
sim> d r10 9
sim> d r11 0
sim> run 2
Where copy and boot were extracted from srcsys.tar on the distribution
tape. I guess on real hardware you would need to somehow get those
files onto whatever the console media is, however that works.

I used VMS to copy them to the console media when I was getting my
11/780 booted, because that was the most convenient way I had of
putting files on an RX01 (it has a DEUNA). The commands listed pretty
closely mirror what you'd type on the console, or put into
an "indirect" (aka script) file on the console media.

I think 5MB is correct. And don't they use the same memory array boards as
the PDP-11/70?

I do have a number (4 I *think*) Emulex Unibus SMD controllers. I
also have a fair number of the "big" Eagle drives. Let me know if
anyone's interested.

No, but I have a, 11/725 in the corner I need to diskify and get
working again.
I don't mean to bring up the "how crappy RC25s are" thread, but I
either need a cartridge (so I can spin up the internal drive, too), or
a workable Unibus disk solution (SCSI or SDI or ESDI - I doubt the
11/725 can take a UDA50 internally due to power or heat issues). I'm
also open to exotic suggestions, but back in the day, I remember being
pinched for "creative" Unibus disk solutions.

Yes, I did it a few years ago and it worked fine for me. As I recall I
ran it on a ra90 with a uda50.
However, I have yet to get netbsd to work. I hacked a version of the
netbsd 1.5 boot to allow me to do nfs copies with a deuna. This allowed
me to install 4.3 over the network (slowly).
netbsd wants more memory than I have and the 730 guts were slightly off.
I've gotten close to fixing it but not yet.

The 11/730Z configuration (same backplane as for the 11/725) only has
room for five 1MB boards. I don't know about the later 11/730
packaging, the one that looks like it's in a BA-11-type box at the top
of a 42" cabinet (reminding me a little of a skinny 11/750). I never
had one of those, and after the limitations of the -Z packaging, was
always curious about it.
The -Z is nice if all you need is a CPU, an RB80 disk, an RL02, 5MB of
memory, a DMF32, and perhaps a tape drive or a couple of SPCs. You
can run an external BA-11 (we did), but having a side-along cabinet
sort-of defeats the purpose of the integrated packaging.
The 11/725 can also be rigged with a BA-11 (I've seen it done, but
haven't done it myself), but it helps to nibble out a notch in the
outer skin to pass the Unibus cable out. Electrically, it works, but
it was never a supported configuration, and there's no pre-made way to
deal with cable issues.
8MB on an 11/750 is adequate for many things. 5MB on a KA730 is much
more constrictive. I know they were balancing models and trying not
to cannibalize high-end customers on a cheaper package, but we found
memory, not CPU speed (slow as it is) to be the ultimate limiting
factor with those models.

How much memory does your system have? I'd love to see NetBSD on the
11/730.

good question. it's been a few years. I think it originally had 5mb
with an external box, but i needed some slots for the uda50 and it's now
at 3mb.
(I'll look next week). I know I have 5mb but I think I've been running
with 3.
I have since found a scsi unibus controller so I can add more memory.
I think my next attempts at netbsd will be using that since loading
via the network was pretty slow.

If you install <1.5, 4MB should be enough, right?
