I've not looked at one for a while, but that makes more sense. Presumably
the 6522 is mapped into the Beeb's 1MHz bus space.

Oh, then I stand corrected. The Tube is the only 40-pin connector on a
Beeb.

Anyway, I noticed that one of the big electronic surplus places had tons of TOPS network stuff ~5 years ago.
I think it was Alltronics in San Jose, but I am not sure.

Subject: Vintage equipt
Dear John, I am trying to find vintage mac networking equipment,
specifically TOPS Flashbox and TOPS Flashcard. They were used for
interconnecting Macs and PCs around 1991.
Any suggestions would be appreciated.

I picked up an IBM keyboard at the Village des valeurs on saturday. It
has nice tactile feedback, no vanity keys and takes up less desk space then
my aged Keytronics. Cool.
However, it "doesn't work". When I plug it in and start the computer, all
3 leds go on, then NumLock goes off and nothing responds as I would expect
(caps, scroll, del to get into bios, ctrl-a for adaptec scsi monitor)
I was under the impression that there were 2 types of keyboards for
clones: PC/XT and AT keyboards. This keyboard has a PS/2 style miniDIN-6
connector (though I now notice it doesn't have the rectangular plug in
the middlish that my other keyboards do), so I assumed it would be AT and
therefore compatible with modern motherboards. No luck :(
Looking on the bottom I see :
Part No : 1395300 IBM
ID No : 2117313
Date : 12-05-1992 (C) IBM Corp. 1984
Plt. No. : WP1 Model : M2
Made in USA
[bar code]
1395300112117313
So, do I have a defective keyboard? Or is this not even a PC keyboard but
for some other piece of equipement?

Well, for one thing I'd want multiuser capability, clustering, and the
GUI would have to be improved. I never liked the looks of the Amiga GUI;
it looked primitive to me. I haven't seen an Amiga lately, so I don't
now if the looks of the GUI ever improved.
I use a GUI primarily to manage several text windows, so I could ignore
most of the GUI anyway, but the text displays would have to be fixed.
And the OS should not require a GUI for system operation. I like my
systems to be connected to a terminal server with one main system
acting as the terminal (along with my VT525).

Hi all...
I have been trying to bring my Next station to complete working shape...
I have "restored" and tested the CRT on the N4000 (part no 135.00) MegaPixel
monitor and seems to be ok on a Sencore CRT tester...dont think it would
last for years now but should be giving a picture....
But I am still without a picture.
When power is turned on, I can hear the HV "crackle" for a fraction of a
second but then no HV.
I dont know if someone played around in this monitor but on the verticaly
mounted board ("analog board"?) C57 and C201B (top near flyback) are
missing...anybody got one open or schematics to tell me if they should be
there and the values?
There seems to have been some soldering work there -- but hard to tell...
Kinda weird cause these are the two only empty parts locations in the whole
board...
Thanks

OK, my neighbor just dumped a B400X expansion chassis on me (unfortunatly
he's keeping the VAX 4000-100). Is the backplane straight Q-Bus? I'm
wanting to see about stuffing a VAX 3400 boardset in there (that he also
gave me). I'm assuming I can't stick something like a 4000-300 boardset in
it (really don't know as I've not had access to something like that), or do
they plug directly into the Q-Bus?

This morning a truck arrived with a box for me weighing about
140lbs. :-)
Please note: quite some time ago, I mentioned ordering something from
a company called Techs R Us, in Texas, via E-Bay that, hadn't arrived
yet. There was a reason for the (very) long delay in the shipping of
this computer system; the lady who owns the computer business selling
it had a health problem and was unable to ship it at the time. That
apparently explains negative feedback on E-bay for her company. She's
a very pleasant person to speak with, and does return telephone calls,
although not always right away... so, if you order anything from her,
please be patient. It may take a long time to arrive, but you should
receive it. What I received today arrived in excellent physical
condition; not even a dent in the packing box. Has anyone on this
list been to her store in Dallas Texas?
The aforementioned system was sent via Craters and Freighters, and USF
Worldwide delivered it after they called ahead a couple of days
ago. The two men on the truck asked where I wanted it, and they
carefully placed the box in that location. Much better service than
UPS!
After pulling all of the heavy wire staples out, opening up the box,
removing big pieces of styrofoam and lots of foam packing chips, a VAX
4000-200 in heavy bubble wrap became visible.
After extracting the VAX from the box and unwrapping it, I discovered
the following: a rather ordinary VAX with what appears to be 16MB of
RAM, a KA660 CPU and two 300MB DSSI disks... and other interesting
bits described below.
Seeing what appeared to be terminated miniature SCSI connetor and a
centronics connector, I was hoping to find a SCSI board in the system, but
no such luck.
...what I did find, however: a dual height board labeled "Talon
Technology Corporation" connected to a DB15 connector. This board has
various numbers on it; not sure which one the model number is. Some
of the numbers are: 100501-2, 01B14 and 1242344. Does anyone know
what sort of critter this board is?
The other somewhat interesting find: a set of boards labeled M3135-01,
M3135-02 and M3136. The M3135 boards appear to be something called
DECVoice and the M3136 connects the M3135 to T1 telephone service. Is
anyone familiar with these? It is correct to guess that this won't
work with a regular home telephone line?
Once I finish disassembling it, extract any spiders and move it inside
the house, I'll check it out, and see if it boots up. ...that is, if
I can find any place to put it, which I should have thought of before
buying it many months ago. Alas, it has neither a tape drive nor a
CD-ROM drive. There's one cable that looks like the type that
attaches to to a TK50 or TK70 drive, but no power connector in sight.
Am I going to need a tray for the tape drive that plugs into the
sockets on the backplane?

Excellent analogy!! Somebody falls in your insecure pool and YOU are at
