Bering 7320SC Econopac Hard Drive Item number: 180230181732
The drive isn't mentioned in their current (2005) Econopac list.

3rd party HP-IB => SCSI et al disk hardware - I wonder if any of them
would consider releasing their code for the HP-IB emulation under an
Open Source, Hobbyist or Non-compete license. I wonder too whether they
have HP-IB device protocol manuals that could be scanned for bitsavers.

I've been thinking about some of the later versions of Research Unix,
such as v9 and v10. If I could track down install tapes/disks, would I
be able to run it on my VAXstation 4000-60? It seems that post-v7
didn't spread very far, so I guess I won't be too surprised if nobody

Hello fellow collectors,
University is about to clean out storage space and there are a few older Sun workstations which will probably get their tickets:
4x SPARCstation 10
2x SPARCstation 20
5x Ultra 5 (both sBus and UPA versions)
2x Ultra 10 (or so)
I did peek inside and didn't find anything particularly exciting (e.g. matched processors or unusual boards) so I suppose they will not warrant shipping and would have to be picked up at Erlangen University, southern Germany. Some do have memory and disks installed, others were robbed.

Does anyone here have any ideas on how one would go about converting a

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
Q: What is the most annoying thing in e-mail?
I guess my first question would be -
If you're running on an 11/83 under RSTS/E,
why WOULDN'T you want to use 22-bit addressing?
Surely you're not "wasting" a perfectly good 11/83 on V6C or V7.0 ?
But, to answer your question -
My interpretation is that you can:
Use 22-bit addressing, in which case RSTS/E (V8.0 and above)
will see the controller as a TSV05, and will use 22-bit addressing
to access memory above 256K (when applicable).
You'll note that if you do a HAR LIST under RSTS/E V8.0 or above,
it will flag this drive as "extended features enabled", indicating that
it can use the full 22-bit address range.
Set 18-bit addressing, in which case RSTS/E (V7.0)
will see the controller as a TS11, which will ONLY be able to access
256K of memory without modification to the device driver.
(V8.0 and above might (properly) recognize it as a TSV05 either way,
however, the "extended features" will be disabled, and it will only be
able to access 256K of memory.)
If I left anything out, I'm sure someone will chime in. . . .

Guilty as charged on the 11M+ part. :-)
However, I think I covered machines without MMUs as well, I just didn't spell it
Without MMUs are the same as machines with the MMU disabled.
The one thing that differs is who puts out the extra bits on the address bus if
there are more than 16 address bits, when you don't have an MMU.
The CPU do, in those machines.
Oh well. And I thought I'd done a real proper job. :-)

I am dumping my small collection. If anybody is interested and is able to
pick it up, you are welcome to get it. I do not ship or store. It was a
complete microvax 3800 (upgraded to 3900) but I took the KA655 to fix my
barebone 3900. You get the computer with RA7? DISK, DSSI disk controller,
memory, ethernet card, tape card and tape drive. Plug in a KA655 and it is
ready to go.

Some time ago (two months? I forget) someone sent me the "LA180
DECprinter I Maintenance Manual" to scan. Thanks to the good offices
of our very own Dave Dunfield, the 8?x11 pages were easy. I finally
went through the foldout pages, scanning them with my flatbed. What I
have not done: (1) where two scans were necessary to cover a whole page
(which was true of most of the foldout pages), I have not merged the
two scans into a single image file; (2) I have not interfiled them into
the PDF, largely because I've never bothered to create/find PDF
building/busting tools (the only PDF-aware software I have at hand is
However, the information is all there. See
ftp.rodents.montreal.qc.ca:/mouse/docs/DEC/LA180/ - the .pdf is the
8?x11 scans; the scan.%03d.bz2 files are the scans of the foldout
pages. I think the pages are in order - that is, if page N is before
page M, all scans of page N have lower numbers than any scan of page M.
Anyone who cares to is welcome to pick them up and put them somewhere
more appropriate, like bitsavers - I suspect anyone doing that would
want to do the things I mentioned above I didn't do, but, well, that
calls for a Princess Bride quote.[%]
Most of my scans were 300dpi 1bpp line-art scans. Two pages came out
quite horrible when done that way; those I scanned as greyscale - you
can identify them by the file sizes (scan numbers 003/004 and 022/023,
as it happens).
Some small number of my scans (two, I think) actually fit on an 8?x11
page, just sideways. Those scans have been rotated so they're
right-ways-up when the image file is viewed the usual way.
My scans are bzip2ed PBM (for the 1bpp) or PGM (for the greyscale)
files. If someone needs something else, like TIFF or GIF, let me know
and I'll see what I can do. Unfortunately the FTP daemon I'm running,
while it supports conversion on request, does not grok *removing*
suffixes to generate requested files. If you need bunzip2ed versions
for some reason, let me know and I'll see what I can do.
I still have the dead-tree version, so if you find anything that needs
rescanning or any such, it's not out of the question.

Hey folks. I'm trying to get an Overland Data OD3610 drive
working with a Dilog DQ132 controller in a PDP-11/83 running RSTS/E.
The DQ132 manual documents dipswitch S8 as enabling 22-bit
addressing, and it defaults to disabled. Here's the relevant
paragraph from the manual:
Switch S8 selects between 18- and 22-bit addressing. Only the
TSV05 software handler supports 22-bit addressing on the Q Bus. The
TS11/TU80 handler may require modifications to support 22-bit
addressing on the Q Bus. Default value is S8 ON, selecting 18-bit
main memory addressing.
So am I to assume that it can be used as a TS11 in a 22-bit
system, and the driver uses bounce buffers? Any idea?

Its not test gear that's the problem its access to the board. My Tek
465 will trigger on single pulses with no problem.
However whilst it's recommended that the the first CPU board (the 8330)
be in slot 2 (The front panel is in No1) its not mandatory. So I can
move the boards back a bit and get to the front of the 8330.
Manual I have, (very good) Schematics also (Awful) so bad I may even
redraw at least the 8330. I have an A0 HP plotter so its easy to do

I'm even luckier in that I live near enough to Cricklewood Electronics

I don;t know what test gear you have, but I find a simple logic probe to
be more use than a 'scope for this sort of problem. The former can
easily detect narrow pulses that are difficult, if not impossible, to
see on a non-storage 'scope. Of course an 'Advanded Logic Probe' as HP
called the LogicDart is even nicer, but...
Do you have the maintenance manual? Not the printset (schematics), but
the book which is a low-level circuit description? It's well worth
I would have thought it wouldn't be too hard to keep on hitting the DEP
key and seeing what, if any Omnius signals are generated. And then
totrace back the missing one(s).

Any reason you';ve not fixed those? Ticking SMPSUs are often quite
simple to fix, maybe just dried-up capacitors.
