Hi,
I spotted three old HP disk (and disk/tape) drives
indoors at a salvage yard (Heillman Salvage) in Atascadero,
California(about 170 miles south of the SF Bay Area):
HP 7914
HP 7908
HP 7911
They didn't look like they're in immediate danger of
destruction (they're currently working on breaking up a Cray 2 ...
no, they didn't have the entire machine ... apparently,
the Computer History Museum got the CPU, and Heillman got most of
the rest).
The HP drives were a bit dirty, and I have no idea
of the price. The phone number is 1-805-466-4893.
Also spotted (outside): carcass of a Lisa (3.5" drive, no faceplate),
a badly burned HP 9845, a probably stripped CE control panel for
some 12 bit computer (no brand name visible, had a rotary dial with
a semi-transparent plastic disk in lower-left corner of
panel ... couldn't get close enough to read anything).

Anyone know if anyone still makes DC-100 tape cartridges any more? I'll
be getting an HP-85 soon & I want to find a source for blank DC-100 tape
cartridges.
My searching so far has turned up nil, but maybe I'm just looking in the
wrong places.
Any help is more than welcome.

Hi,
I received the following two-part email this week...
A free 9835...
...
I moved up to an HP 9835.
[It's in Canada]
...
Now the good news, I still have the 9835 in my basement. I think it's
still close to being
functional, it turns on without clouds of blue smoke but the monitor
appears to have given up so no way of seeing if it is really booting
up. I'm not sure about the tape drive?
If you could locate a monitor, maybe you could get a functioning 9835.
It's free to a good home
And, the project:
I have been looking everywhere for anyone who might have a functioning
9835/45 because I still have about 10 tapes with thousands of pages of
HP BASIC that I would love to off load to some form of modern media in
ASCII and translate into modern BASIC. If you could help me with this
problem I would even pay the shipping of the 9835 to you, if you are
interested?
Anyone interested, reply (offline) to me, and I'll pass the contact info
on to you.
thanks,
Stan
Hi, I'm still wondering if I'm left the only one actively messing
around with a VAX 11/780, because all the help I get comes
>from PDP-11 people ... but that's adequate since I am still
debugging the UNIBUS.
I now made sure the NPG line is interrupted under the M7486 part
of the UDA50 adapter set. Now I no longer get a 3 on the M7485's
LEDs but it properly goes up to the 4/5 blink. Even the port light
on my RA90 lights up so that it feels like it's going to come up
any minute. But it doesn't. The VAX console never shows any
sign of life, the RUN light goes off and the M7485's LEDs show a
constant 5 (no more blinking 4/5). Then the drive's port light
goes off too.
When I interrupt the console and UNJAM it says "HALTED AT 000007B7"
The interesting thing is that I can set the R3 register (that
indicates the device unit on the UDA50) to a different value (my
drive is set as unit 0) and indeed the drive's port light never
lights up, as it should. However, the machine hangs in the exact
same way and when I interrupt it, it comes up at the exact same
address 000007B7. Would that mean that we get stuck even before
the boot sector is loaded from the disk?
I have two straws of hope to hold on. One is that the basic
diagnostics tells me that KA780 module M8230 fails. So I can
replace that once I have a spare. The other hope is that my
UNIBUS isn't properly terminated.
I have what looks like a UNIBUS terminator card but whenever
I plug that in, the UDA50 acts strangely and effectively never
reacts to the host at all, just constant cycling pattern as
if nothing ever happened. Also, my level 2 diagnostics fails
when this terminator card in is. When I remove that terminator
I see at least the UDA50 and host communicating a little as
described above. And without terminator the diagnostics level
2 finishes flawlessly.
How essential is the UNIBUS terminator? Does the missing
terminator explain why the host hangs and silently stops
during boot? I never get a machine check or anything.
Or, am I just impatient??????? I do know from my other VAXen
(6400) that they turn on all fail lights and make the
drive's port LED go off during the first phase of the booting
activity. Could it be that the VAX 11/780 just needs several
minutes for this job? I don't think so...
Who knows what the address 7B7 in
Thanks,

PS: this is what the DUABOO.CMD does:
EXAMINE SP ! SHOW ADDRESS OF WORKING MEMORY+^X200
G 0000000E 00000200
LOAD VMB.EXE/START:@ ! LOAD PRIMARY BOOTSTRAP
LOAD DONE, 00004800 BYTES LOADED
START @ ! AND START IT
does that mean the VMB.EXE is loaded at 00000200, so that
00000747 is relative address 547 in VMB.EXE? Is there
a commented disassembly listing for VMB.EXE somewhere?
Hi All !!
A good haul at the local University auction has netted me
a coupla Sun Ulta2's, a few vt420 monitors an IBM3151 terminal
and the neatest find in the last few months....
A russian pdp-11.
It appears to be an exact replica of a dec professional 350.
It has the same case as the decmate/ rainbow/professional series.
All the labels, everything, is in cyrillic, but it is an exact replica
of my 350, the only difference is that instead of the funky
dec dual RX50, it has two ordinary looking 51/4 floppies,
and the color is what my friend calls a soyuz silver or moscow gray,
as opposed to the dec beige/sand.
It has what appears to be a RD50/52 but it is all labeled in russian.
It even has the CTI bus cage with the cards for the drives.
On sliding the mainboard out, it is identical to my 350, except
for a few oddities, and all the chips are labeled in cyrillic!.
It dates from 1988 and seems to be in excellent condition, except for
the upper plastic cover is missing the front plate.
I was really tempted to fire it up, as it appears to have, an US style
110 power receptical. But second thoughts, made me cautious as
I'm not sure of its electrical requirements and would hate to toast the power
supply or boards as it is a bit different from the 350 in size and various
connectors.
If anybody has seen one of these or has info, I'd apreciate a little help!!
In the mean time I'll did up my russian-english dictionary and
maybe try to trans-literate the cyrillic characters.
Cheers

I have a fair condition DEC LA-120 printer available for free. It needs a
bit of cleanup, but it does work just fine. Available for pickup in the S.F.
Bay area. Otherwise you need to pay for the shipping.
First come, first serve. Let me know.
Thanks,
Bill
I've been working on trying to get a pair of TRS-80 systems transferred
>from Southern RI to sunny NorCal but I'm finding that the extent of the
collection makes it prohibitively expensive to pack and ship (5 boxes of
stuff from what I'm told).
Is there anyone in the RI area interested in rescuing a TRS-80 Model III
and a TRS-80 Model 1000SX (Early PC Clone)? There are peripherals (at
least one printer, for instance) and lots of docs and software for
these.
I'm just trying to back gracefully out of the deal without leaving the
donor hanging. I've belatedly realized that I can't justify the expense
of shipping these relatively common systems from coast to coast.
Please contact me if you've got an interest and I'll do what I can to
set you up.

Hi Nico,
Yes, they are 9 track reel to reels.

do you mean Microsoft Basic Professional development system version 7 and 7.1?
there's also Visual basic for dos Version 1.0 which came after QB 4.5
