Tim.
I've just been shown a load of HP 3000 and HP 1000 gear which
is about to be thrown out, located in Bristol (UK). This
list is approximately what's available:
HP 3000 Series II
7970 B Digital Tape Unit
7970 E Digital Tape Unit
Metier 50 Megabyte Data Storage Unit (disk)
HP 3000 Series III
97935 top loading disk drive
7970 E Digital Tape Unit
HP 1000 E-series computer "Artemis System"
12979 B I/O Extender
7906 Disk Drive
13037 Disk Controller
2648 A Graphics Terminal
2631 B Line Printer
unknown modem
2392 Terminal (qty 3)
Flexible disk drive for HP desktop calculator (qty 2)
Falco Terminal
91148 Floppy Disk Drive
Alignment packs for HP 7905/7906 disk drives
They want to clear out the storage space quite soon, and if
anybody wants any of it, we'll have to arrange something quite
quickly. Most of the computers are in 19-inch racks of about
5-foot (1.8metre) height, but some of them are double-width
racks. Basically, you'll need a van to move them!
Any takers?

I grabbed this yesterday at goodwill. It looks like an
HP-IB/floppy-IDE interface, but I can't find any references.
HP model appears to be:
09L Rev C
09153-66511
or
2815
or
0TF0C07
or
RSWKC3
The card has a bulkhead plate w/ HP-IB connector, address dial switch
0-9, and configuration dial switch 0-9.
PCB itself is about 10" by 3" with a 1.5" by 3" cutout. There is a
34-pin male and a 40-pin male header and dip switches:
TEST <--> NORM
B <--> C
30/40 <--> 10/20
BOTH <
10/30 <--> 20/40
NO FLOPPY <--> FLOPPY
What is it?

Nope, It's an LSI-11/02 Qbus machine woith a small cage and rack
and RX01(maybe an 02). You need Qbus for the varions analog IO
and digitial IO cards.

The PDT11/150 has no user bus and the oly IO is serial. It is however
the same LSI-11 chip set but no provision for the EIS/FIS. Yes, I know
you can piggy back one of the microms to do that but the board only
has 4 40 pin sockets that are filled where the LSI-11/03 Qbus board has 5.

No, it doesn't even have a serial port (yuk yuk).
If you'd like to turn your favorite 486 into a ZX81 there are ZX81
emulators for Linux, but to my knowledge no one has even entertained the
idea of doing some flavor of Unix on ZX81 hardware.
Hmm, now thatcha mention it, Linux makes more sense than Windows or GEM,
CP/M's already been done, VMS ain't happening here, and I *really* don't

After considering this, I think you've hit the nail on the head, Joe,
except that the only thing we don't change is the engine! The Z80, ROM and
ULA *have* to be present!
Our goals seem to be:
1 -- Build an interface for every device under the sun, including the
toilet seat.
2 -- Write software to perform every task ever performed by any computer
anywhere. The software should be 100% Z80 machine code and should push the
ZX81 as hard as possible.
3 -- Do all of the above for US $25 or less.
I hope everyone has as much fun with their old computers as I have with
mine!

DEC's destruction began when DEC was palmerized into a ghost of it's
former self and sold into slavery to Microsoft. Then much damage to
this once great computer company, DEC, was done by Compaq (a wannabe
computer company that never made real computers, and destroyed an
acquisition, DEC, that did), and, now, this appears to be little more
than the nails being hammered into the coffin of what was once Digital
Equipment Corporation.

Hi there,
I've recently acquired a set of SGI dials and buttons. These are two units:
The dialbox has SGI P/N 9980992 and is manufactured by Danaher Controls with
Model # DLS80-1022. The buttonbox has SGI P/N 9980991 and is manufactured by
Advanced Input Devices with Model # CMN B018B.
I have not received any cabling with the units and also I have no power
supply. Using google, I could not find any useful information on how these
units are expected to be supplied with power. There are some references to
SGI boxes which provide for power supply on some serial ports, but these where
pretty unspecific and did not reference these exact models.
Does anyone reading this have a set of these and can help me with getting the
pinout and the expected voltages for the power supply for these units?
Thanks in advance,
Hans

Ok, I'll agree that it can and does, since I am
unfortunately forced to use it by corporate edict. :(
I will argue that it's not "easy" to turn off. "Easy"
would be a button that says "don't ever post a message
with HTML." There is no such option. It must be turned
off as a default, and then still on a per message basis
every time you don't want to respond to somebody who's
used HTML with another HTML message.
So I will agree completely with you if you will replace
"easy" with "cumbersome at best."

I have the following junk^H^H^H^H R@RE computers for anyone who wants them.
Pick up in Chicago or pay shipping costs. Most are untested and might not
work, all are dumpster finds:
(in order from largest/heaviest to smallest/lightest)
HP Portable Vectra
Toshiba 3100e/40 (power light comes on, but does not boot)
NEC MultiSpeed EL
TI TravelMate 4000M (color LCD, 486 DX4/75, but was found partially
disassembled, so most likely does not work)
AST PowerExec 3/25SL (no hard drive)
Tandon NB386/SX (has loose/cracked hinge, but is the only one with its power
brick)
Kenitec (no model number; probably XT compatible)
I also have an NEC MultiSpin SCSI CR-ROM reader, external.
Again, I don't know if any of these work, but if you've ever wanted to tear
apart a portable, or play with an LCD screen, they might fit the bill.

It's my opinion that Compaq will be pissed away by HP just as Compaq pissed
away DEC.
I never really did *love* Compaq, mainly because they are a PC company.
They make good PC's, but I hate PC's.
The real problem is that several thousand employees are going to get the
axe because of a power trip by an HP CEO.
I love to see someone who actually believes that the "new" HP will compete
with IBM.

I have winder boxen that do that as servers. As desktops forget it, Word

Yes, it could. Shame the CPU was idle or doing just the block move.
I've seen Qbus systems (PDP-11) sustain levels like that but, the
CPU was useful.
PCs, and their busses didn't allow for concurrentcy of operations
especially ISA.

Ultrix was not nearly as well developed as VMS for multiple CPU
and cluster configs. Available user performance on a 6k system
with decent disks was very high under VMS but under ultrix is
was a less appealing system. I'd used an identical pair while at
DEC with both ultrix and VMS and the ultrix system was a bit doggy
even at lighter user loads (no one liked it).
Comparing it to a 486... no contest with a pot load of users. the
i486 does not have the system robustness and IO capability.

While we're on the subject, I do think the [OL] idea is a good one,
but I just wanted to add my tuppence worth on the subject...
The address I post from isn't always the same as the one I read it from;
I tend to choose the address to post from (work or home) as appropriate
to the content of the message... If we go with the tagging off-list
posts, it would be nice if there was a way of registering additional
'posting addresses' as well as the subscription address.
Not essential, of course, but would be handy (would be more
essential if we got to the stage of actively blocking off-list posts.)
Incidentally, I'm all in favour of the blocking HTML, by the way...
Cheers,
Tim.

Tim Walls at home in Croydon - Reply to tim(a)snowgoons.fsnet.co.uk
It is very contemplative to sit in the basement, room filled with
big iron and lots of blower and disk noise, and watch the system
creep ahead compiling stuff. I remember those old days back in, say,
1994 when I sat there on a i486/33 watching GCC compile (and those
*endless* runs of all the fix-include stuff.) What surprizes me is
that the feeling on a 1989 vintage 6-processor million-dollar VAX
isn't very different! I expected it to be faster with that.
So I looked at statistics. Nothing paged out (0.5 GB of RAM),
but looks like the system is heavily I/O bound and I/O
is quite slow. I even distributed disk load over 3 RA90, though all on
the same controller, but at least that's a KDM70, directly on the XMI
bus. Still, disk access seems just a bit on the slow side. Why?
All terminal I/O went through the Ethernet, which I thought was a
DEBNT but is reported to me as a DEBNA. Anyway, that's just the
few lines of text that are being logged as make creeps forward with
its job.
Looked at cpustat (we're on Ultrix 4.5 BTW), where you can see the
load on the CPUs. Sorry, no "screenshot" here, but in short it lists
6 CPU's and the load on each. 5 of them tend to be 97% idle and CPU#1
is 75% idle. CPU #1 gets bombarded with all interrupt requests while
the others get none of that. Unfortunately I couldn't figure out how
one can see process to CPU allocation. I suppose that each process
runs in a single thread on one CPU every time it is active. Since the
making and the cc-ing is a sequential thing writing temporary files
to disk, I suppose that the 5 idle processors have nothing to do
while CPU#1 takes all the burden of the compiling task plus all
other system interrupts (essentiall all I/O.) So, that's kind of
not optimal.
I suppose, once I have my first GCC built I should use the -pipe
option to avoid temporary files with the hope that the two ends
of each pipe would then be allocated to two different CPUs. That
should then speed up the process a lot, basically could stream cpp
on CPU#1 to cc1 on CPU#2 to as on CPU#3 right through. I hope. That
is, if UNIX domain sockets (i.e. pipes) are implemented so as to not
require any hardware IO. I *hope* this is simply done by CPU#1
entering kernel with an mbuf and CPU#2 entering kernel shortly
thereafter reading that mbuf, so only memory should be involved.
It's interesting. At some time soon, may be early this summer,
I'll give a VAX party where one of the highlights will be a
race between my i486/33 and the 6460 in compiling something,
there we can see if it's really just my perception that the
6460 is kind of slow for the price, even measured by past
standards.
Another thing that made me wonder is that writing to the TU81+
on KLESI-B showed its signs of I/O bottlenecks. When I just
did
# tar cvb 20 -f /dev/nrmt0h /usr5/gcc-2.7.2
the tape would write block by block in staccato and would not
stream. The TU81 is still nice even in block mode, not that
endless back and forth of the TK50 or any other cassette media
that I have seen operating, it's a fast staccato tatatatatatata,
you gotta see this!
Only if I used my dd buffering trick with
# tar cvb 20 -f - /usr5/gcc-2.7.2 |dd ibs=2048000 of=/dev/nrmt0h obs=10240
would it stream over larger sections. But the slightest disk
read activity would cause a little pause to the tape transport.
First I thought I should be rearranging my cards on the VAXBI
busses, but then I remembered that the disks are on XMI directly.
So, a simple RA90 read through KDM70 on XML is just not fast
enough in order to keep the VAXBI - KLESIB - TU81+ streaming.
Are the RA90 disks so slow? Or may be it is Ultrix' bad way of
using the multipe CPUs again, i.e., they still handle all the
work through one single CPU#1 while the others are chatting idly?
Does NetBSD do a better job with SMP? Would it use one CPU for
the disk IO and another CPU for the KLESI-B IO with shared
memory buffers in the middle? May be not if I used just one
process to both read from disk and write to tape (like tar
only), but with the pipe, tar | dd it should do it and that
should allow me to use a smaller ibs for dd, AND have real
streaming write to the tape. Or is SMP on NetBSD/VAX still a
sub-optimal hack?
When I attended BSDcon 2002 in San Francisco few weeks ago,
it seemed like all the BSDs would go different ways about SMP.
I liked what Jason announced about NetBSD, like IO being
handled without memory data copies, and the kernel actually
shrinking in size. I would hope that all BSD/SMP efforts
nowadays seek to allow true load sharing between the CPUs
and not shedule IRQs to only one and not hog that one primary
I/O CPU with *all* processes that have any I/O to do. And
I sure hope that it will be natural for pipelined processes
to operate on different CPUs. Right?
regards,
-Gunther
