Well that certainly explains why the chip never saw the light of day;
Bill G. must have stomped all over this one. Porting Windows to it
would have proved impossible, since pretty much the entire Windows
system is 'garbage'. :^>

This week had a fine start. I walked into a little computer shop which has
trays of old ISA cards and sometimes odd equipment which I can buy cheaply.
This monday, they had a slightly familiar-looking box on top of a large
shipment of PCs. A HP 9000/300! When I asked them what it would cost, they
were surprised that they could even charge money for it, and let me have it
for 50 crowns. My pleasure. Once I had bought it, though, I though that
9000/300 was a suspiciously low number. Wasn't that some kind of 68010 based
machine? And why would such a machine have two Ethernet NICs? It really semed
like a waste, but on the underground ride how, I pulled out the big board with
all the ports, which seemed notably shinier and newer than the NIC above, and
found that it had a 68040. I thus deducted that it must be a 9000/380. Has
this machine been upgraded, or did HP simply not bother to identify their
machines any closer than the series (in this case 9000/300)?
In any case, it came without keyboard, and I read that in order to switch it
over to serial terminal mode, one would have to perform a certain manoeuvre
via the keyboard. Bloody well thought out, HP! Is there no way to use a serial
terminal without any HIL keyboard involved?
The machine starts up and beeps a little. It's got not drives installed, but
there's a 50-pin "Centronics" connector marked SCSI/FS-HPIB. What is FS-HPIB?
Doesn't sound like anything I'd like to feed into my SCSI devices.

Hi,
I picked up an Acorn RiscPC 600 base unit the other day, my first Archimedes-
type Acorn machine.
Anyway, I have a few questions. Perhaps someone can point me to a decent web
site about the Acorn machines?
- I'm assuming the RiscPC 600 uses an Archimedes-type mouse. This should not
be a major problem, as a simple pin-to-pin adapter should allow a three-
button Amiga mouse to be connected.
- Can I use a PS/2 type PC keyboard, or is a custom Acorn keyboard needed?
- Before powering it up, I want to remove the hard disk and create an image
file of its contents. The CD-ROM drive needs to be removed in order to get
to the hard disk. I can't see how to do that. Any ideas?

Hi --
I'm cleaning out closets here, and I've come across a copy of SCO
Open Desktop 1.0.0 (!) on 5.25" disks. I've no idea where it came
from, but that's the case with a *lot* of the stuff in this
closet. :-)
Anyhow, if someone would find this interesting/useful, it's yours. I'd
prefer you pay shipping, just so I'm not actually *losing* money on
it. :-) It's a 9 x 9 x 6 1/2" box, weighs five lbs or so (75% manuals,
25% floppies, in three still-sealed floppy-boxes!).
"System requirements:
For 386 or 486 computers based on Industry Standard Architechture
or Extended Industry Standard Architecture.
Minimum requirements include: 6.0 MB of memory; 100 MB of disk
space; EGA, VGA, Extended VGA, Herculese Monochrome, or selected
high-performance adapter; Bus or serial mouse (recommended); and,
3C501, 3C503, 3C523 or WD8003E Network Card (optional)."
It's never been used, so you get the license and activation keys as
well. It's marked "FOR SHIPMENT WITHIN THE U.S. AND CANADA ONLY", so I
can't guarantee you'll have a legal license if youre not there.
Quickly reading over the blurb, it's got LAN Manager and MS-DOS
support, X11, and an unknown DBMS includeed, and "unleashes the full
power of 386 and 486 machines". Zowie!
Anyhow, drop me a line if you want it. It'll go to the first person to
offer to pay shipping, or, if no-one does, to the first person that's
not too expensive to send to. :-)

new!), try <rich(a)alcor.concordia.ca>.)

Be careful here...Some NeXTs use ADB and some don't. And yes, you

The DSP port didn't have any set purpose. It's a high-speed
synchronous port with a directt path to the machine's DSP chip. It's
been used for many things including high-quality video and audio I/O
and stuff like that. I've seen many home-brew lab experiments using
that port also, both in personal applications as well as in
laboratories. One popular application involved building an interface
to connecting a glove-like input device (PowerGlove or something like
that) to the DSP port and use it for virtual-reality-like
experimentation.

Those serial ports use the same pinouts as Macs and Sun IPC/IPX

One can construct a breakout cable, but then you'd have to come up

NeXT monitors are neither expensive nor difficult to find. It's

Two products called "Digital Eyes" and "Digital Ears", that allowed
for video and audio digitization. Also the DayDream box, a small box
that basically turned your NeXT into a Mac Quadra if you booted the
right kernel. Those were the only commercial products that I've seen,
though there have been rumors of others.

Being a Turbo NeXT (either color or mono) does NOT mean it's an ADB
NeXT. Indeed, I've a stack of color turbos here that are most
certainly not ADB.

Not my Sharp - it works with some of the graphics commands (not AXIS or Text

How about putting a bit of copper wire over the crack, squeezing the gear
together, heating the wire up with a soldering iron, pushing the wire into
the plastic and cutting off the excess? Or it might be possible to use a
metal staple or two. Should be quite strong.

It may be off topic, so let me ask that people send replies directly, but I
just picked up this Thinkpad and docking station at Dayton and am looking
for information on the docking station. It's the one with the speakers that
stick out like Mickey Mouse ears on both sides. It appears to have an
internal SCSI adapter, some odd, high-density ribbon connectors (26 pin,
50 pin and 60 pin), and a slot for a CD-ROM. I'd love to enhance this thing
just a little bit, at least enough to use it for Linux (16Mb RAM, 800Mb disk).
Any pointers to docking station resources are appreciated. I am also looking

...which doesn't connect to the DSP port. It connects to the
video/kbd/audio connector on color NeXT machines. The NeXT soundbox
isn't used on mono machines because the speakers and audio connectors
(and sometimes the mic, depending on version) are built into the
monitor.

That said, actually the better makes of D-connector are rated for
quite
high voltages (500V and above). They were used on valved equipment,
for
example. So I you could use a D connector for mains, not that I
would, of
course.
9 pin D connectors were quite common for mains on BBC equipment but only on
backplanes for
slot mounted units, never as flying leads.

I'm still cleaning house and I've just finished listing a bunch
of video tapes on E-bay. These tapes were for sales and/or service
training for several of the old PCs, including the AT&T 6300, Compaq
Portable II, Compaq Portable 286, Compaq Deskpro, Compaq Deskpro 286 and
the DEC Rainbow 100 and 100+. There are also a bunch of various tapes from
the old ComputerLand stores. All of these tapes were propriatary and were
only supposed to be viewed by authorized dealers. Consequently they are
very hard to find. These are top quality tapes and are very informative.

Are you sure? AFAIK, all Amiga mice are dumb quadrature mice with two
buttons, and their interface consists of 5V power, ground, four quadrature
signals (2 for X and 2 for Y) and two button signals. A Sun mouse has a
proprietary encoded interface that uses three (or four?) wires. I suppose
you could rig one up to a serial port, if you wrote a suitable driver
(might also need a level translator).

Mine is in the smae workshop. Not ideal, but I'm careful where I let the
swarf go (metal swarf is quite heavy so it's not too hard) and where I lay
disk packs. Now the arc welder is a different story. The spatter from
that can go everywhere, so it's in the garage not the workshop/computer
room.

There's a web page somewhere describing exactly how to do that for a
Microsoft mouse.

Oh, it was definitley HTML. Encoded as "[ Attachment
(multipart/alternative): 3829 bytes ]", so if you had HTML display turned
off in Eudora, it probably just showed you the flat-ASCII version, which
was there as well as the cruft.

Good for you.
I've got one too - 16MBs of RAM, ARM610 CPU - and it runs rings round my

Yup. It uses an Acorn quadrature mouse. Available from www.castle.org.uk.

Yes, the Acorn k/b is a standard PS/2 keyboard.

There are two long L-shaped locking pins that hold the case together at the
back and two near the front of the slice. Pull the back L-clips out and look
for two circular clips with small (3mm or so) tags on. Rotate them and pull
them out. Lift off the slice and you can get at the HD. It will probably be
a standard IDE interface.
If you really want to get help with this machine, try joining up to the
newsgroups comp.sys.acorn, comp.sys.acorn.announce, comp.sys.acorn.apps and
comp.sys.acorn.hardware.
Chances are, someone there will be able to help. I'm also a regular in CSA,
CSA.misc, CSA.hardware and CSA.programmer.
If you want, I'll scan in the relevant part of my Risc PC Welcome Guide and
upload it to my i-drive.

Nice find :-) I'm still looking for a Risc PC. I left Acorn about the
time of the A540/R260 and those are the latest Acorn machines I have.

I can't remember for sure when the changes were introduced, but I'm fairly
sure the Risc PC uses a PS/2 keyboard but an Acorn mouse. If so, the
keyboard connector will be 6-pin miniDIN (the older Acorn proprietary
keyboards are also 6-pin miniDIN, though) and the mouse connector will be
9-pin miniDIN.

Sorry, I don't know. I assume you mean how to remove the CD-ROM, not how
to get the case open? I vaguely recall someone asking a similar question
ages ago on comp.sys.acorn (or possibly comp.sys.acorn.hardware) so
searching DejaNews (er, groups.google.com these days) might help.

I know the feeling only too well. I get extremely irritated at stupid
things like this, myself. In fairness to Claude, I don't think he knew
about the domain name rules. It seemed to be a complete surprise to him
when I explained. I understand he originally asked for "computercollector"
but the stupid ISP claimed it was too similar to something else but it was
OK with the underscore (yeah, like the underscore makes all the
difference). That ISP does what mine does: the "nice" personalised URL
that looks like you have your own server is actually an alias to the
canonical name, and the webserver is running virtual servers, translating
xyzzy.tripod.com to members.tripod.com/xyzzy/. So the caonical URL is
legal, but some droid at the ISP forgot (or didn't know) that the alias
wasn't.

My pet hate is typified by pages that use screeds of Javascript to achieve
what could have been does more easily and in 1/4th the space using plain
sensible HTML -- and which fail to load properly on my machine because I
normally have Javascript turned off for safety (it's a Unix box, so the
risk is reduced, but you never know -- and I practically *never* turn Java
on). For an example of the worst kind of page that needlessly complains
when Javascript is disabled, see http://www.enterasys.com/ . It only
fails because the error display gets in the way of the links!

I've had this problem with Claude's pages before (and some others). I even
mailed him about it a while ago. However, I worked out that the
alternative is
http://members.tripod.com/computer_collector/
(the underscore is legal in the directory name, just not in the domain name

Hello...
I've somehow managed to acquire a few Intergraph workstations in my lab.
I've got a 2000, a 2400, and a 6100.
I'm looking for install media for the Clipper UNIX that ran on these machines.
Intergraph doesn't seem to know/care/remember anything about CLiX.
Does anyone have any ideas where I might track media down??
Thanks,

Hi all.
During the weekend I found some time to check the VT102 -> LA210 connection.
The suggestion Tony made, was very good. Stupid that I didn't think of it.
I connected a VT220 to the VT102 printer port using the BC22D cable.
Then I sent characters to the VT220. The letter E showed up as a zero and
some other characters. After that nothing appeared on the VT220 screen.
It was locked up.
Next I connected my Tek 465 to the transmit pin (#2) of the printer port
on the VT102. When I do the printer port test (screen full of E's) and
send that to the printer port it became obvious why the LA210 prints
garbage.
Pin #2 is rougly -19 Volts.
When characters are sent there are only spikes visible with an amplitude
of about 20 V. superimposed on the -19 V.
I hope I did not damage the LA210 as the transmit signal with the spikes
go to almost -40 V.
Or am I making a measurement error?
The pin #2 (transmit) on the VT102 printer port is only connected to the
(high impedance) input of the oscilloscope. The ground of the Tek is
connected to pin #7.
Do I need a resistor between pin #2 and ground (#7)?
Henk.

Too easy :-) The page I saw described removing the serial controller from
a mouse, and wiring straight to the quadrature connections.

1 Amiga 1084S monitor
1 Amiga Ext Floppy
1 Mackintosh (Apple clone maker IIRC) branded composite monitor
3 C64s computers
2 1541 drives
1 1541 II drives
Approx 1000+ floppies of Commodore software
Some original C64 software inbox like Sub Logic Flight Sim for C64...SSIs
Computer Baseball...
2 Fast Load + some other assorted C64 carts
1 Mps801 printer
2 Amiga mice
1 Super Graphix Printer Interface for C64
1 C64 Koala Pad (?)
Several books like : Mapping the Commodore 64, The Best of TorPet (good
reading!) and other books for 6502 programming and similar.
1 Ton of cables and power supplies for all of this
2 Ribbons for the Mps801
1 Sun Mouse (what was that doing in there?)
1 386 clone (he was cleaning out...)

I've been gifted with a PDP-11/53 (or 53+) CPU module.
The CPU is from a DECserver 550, and I have the box as
well, so I'll be able to build up my PDP-11 there rather
than use my BA23 from my MVII. From what I've been able
to determine the CPU modules in the DECserver 550 has
different ROMs, so I'll need to replace them to make
a bootable system. I'll be able to use the Ethernet
card in the DECserver 550 (DELQA), and I'll move over
my RQDX3 and RD54 drives from the MVII. Since the
CPU has 1.5M of RAM I won't need any extra memory
(and from reading the PDP-11 history, adding memory
off-board adds a real performance hit.
So, does any here have a source for bootable ROMs
for this CPU?

Sorry, I have a really bad habit of boiling
things down to as few words as possible. I really
admirer people that can write emails that go on and
on, for page after page.
Anyway, before I get off the track, in 1924 a standards
organization was formed called the Radio Manufacturers
Association (RMA). In 1950, it became the Radio Television
Manufacturers Association (RTMA). In 1953 it was renamed
Radio Electronics Television Manufacturers Association
(RETMA). And in 1957, it was renamed the Electronic
Industries Association (EIA).
Now, Bruce may have said RETMA out of habit when he
meant EIA or these maybe racks from the mid-1950s.
Why do I care?
The mid-1950s were a time of rapid developments in the
field of electronic analog computers. One company,
Philbrick Researches developed an extensive line of
power supplies, amplifiers, manifolds, and other analog
computing components that made to be rack mounted.
Cables interconnected the components in the rack. These
cables used RETMA connectors. These connector are the
diameter of and have pins the size of the base of a
octal pin vacuum tube. Of course the pin spacing is
different. I have a number of these components, but
the connector are difficult to find. That's why my
ears always perk up when I read "RETMA".
I'm just nosing around to see if there is a bin in
back of some surplus store were I might find connectors
like these.
And if anyone comes across any racks that have a tag
saying "GAP/R", I would be VERY interested.

The "GR" (General Radio) sexless connector is pretty common in really
high-frequency stuff, but not quite as common as other (better-built,
more expensive) sexless constant-impedance connectors such as the
APC-7 and APC-3.5.
What sort of connector are you trying to get to?

This is a lucky week for me. After the carload/motherload of Commodore stuff
for $10 now this Model II working with Disk System!
Spotted by a friend on the side of the street.
Advised owner I would pass by and pick it up. I did. It works and quite
restorable : no cracks, major missing parts or evidence someone played in
it!
I am in need of boot disks and software to try it out.
It had one 8" disk in the computer drive and I get a BOOT ERROR TK message
after the computer tries to boot (?) a solenoid seems to bring the head in
close proxymity of the floppy twice after drive goes to outoor most
track...and then I get the message. I suspect the disks in the drive is not
a boot disk, disk bad or a floppy problem...
Head was not moving so I moved the head stepper motor with power off. Step
motor moved back to outside track at boot attempt. So that motor works...
Disk says ACCOUNTS PAYABLE LABELS. Who knows if this should boot......
I am in need of a boot disk and a few software would be nice...
I have also no keyboard. Does anyone know if a keyboard for a Model TRS80
model 2000 will work on this? I have one of those...
I plenty to offer in trade or thank you gift. See trade list on my crappy
