September 26 & 27...Vintage Computer Festival 2.0!
See http://www.siconic.com/vcf for details
[Last web page update: 07/26/98]
Hi everyone. Just to let you know, I'm not dead. (Boos, hissing,
please.) Anyway, I found a MS Softcard for an A2. Serial# (if it
matters) 2-189 18227. Full docs, all disks, packaging, etc. Now, for
someone who has 2 or more: What's a good garage-sale-old-used-hardware
price???? (It's a frends, but I want to pay hm to remove the guilt.)
Pleae reply to worldsfate(a)geocities.com (Yes, that's not this addresss,
but I can't get my HPC to send from it.)
Thanks for any info.
Tim D. Hotze

They don't use corks -- they use pre-bored rubber bungs. However, the
easiest and safest way to put a thermometer into a bung is to insert a
borer first, slide the thermometer down the borer, and remove the borer
leaving the thermometer in place. One of the first things I was taught on
the lab techs course years ago (the second thing was how to deal with a kid
who has a thermometer impaled in the hand).

Actually, you want exactly the opposite if you're cutting it -- a very
acute angle, so the rubber is sliced thinly with minimal effort. You want
to slice it rather in the manner you would do wood turning with a turning
chisel.

Use thick eithernet wire as its coax and uses ground and everything uses
an isolated interface to it. AUI is imune to ground loops and can be
burried.
The other approach is RS422/485 type interconnect as it is differntial.
Myself I'd sink several peices of weather proof coax and build on that
using AUI (thick eithenet).
If you have a choice go underground as air trips invice lightining.

In the workshops I've seen where it's handled, it's usually done with a
very sharp tool with a very acute cutting angle (I've seen razor blades
mounted in a holder for this) and lubricated with glycerine.
For some jobs, I've seen a tubular cutter (rather like a cork borer)
mounted in the tailstock and pressed into the workpiece, similarly
lubricated with glycerine.

Some thoughts:
With many of these devices, it takes (at least) two to tango, and of
course you never find both together. (What is the sound of one statmux
clapping?)
Synchronous modems often didn't just carry the data from one end to
the other, they also provided clock signals to the DTEs. Many DTEs
expect to see those clock signals and won't originate them, so getting
two nearby ones to talk over direct cabling can be an interesting
proposition.
Some of us probably worked with this stuff back in the days when it
was new (1983-1989 in my case). "Fun" is not the adjective that comes
to my mind.

Can you do this over dry copper, for short runs?
If so, would you want to? You mentioned in another post that you'd
have to run conduit for FDDI, and that makes me think there might be
some open space between hither and yon. Sure, you could run copper,
but wouldn't electrical potential differences be a problem?
I know that we used to have a fiber run under the parking lot at the
office, and Ethernet-fiber bridge things at the ends (two buildings
w/parking lot between).

Not a lot, and mostly not by intent. Recently I got an HP9000/220U
with some extra boxes that I believe are a CSU and some flavor of mux.
No, it's not at all clear to me why they were piled together into one
lot; the 9000 didn't have the right sorts of I/O for this.

Thanks to everyone that was helping solve our PDP-11 boot problems but
it seems that part of the problem was the fact that the backplane was
giving out (it actually went up in smoke on friday night while we were
playing with it, as did the front panel to my IMSAI, what a night that
was).
So again, thanks...
Tony Dellett
PS: If anyone in the Massachusetts/New Hampshire area has a spare RX01
that they wouldn't mind parting with, we have alot of Q-Bus cards that
need a backplane :)

The service exists, I used to use it 25 years ago for remote base stations
(radio service). It was called a dry copper pair and went point to point
with NOTHING else. It had to be that way as you would put audio on it and
DC on it to either key the transmitter or disable to tone squelch. the
average circuit resistance ws about 1kohm/mile. So the remote end didn't
sense voltage but instead sensed current (~8-9ma) and polarity to do
switching. Audio was put on the pair the normal way (differential via
transformer).

just a thought, but were these modems ever designed to connect to a
public network? I've got a couple of old BT modems that seem to be
designed to only work on a private, internal network (at least that's
what the manuals imply), so maybe line voltages are different or
whatever...
