Hi folks,
I was just lucky enough to acquire a PT SOL-20 (1976) in great shape to add
to my collection.
Unfortunately, no documentation, I would dearly love to have that, either in
the original or a photocopy
Anybody??
Thanks
Robert

Hello everyone, I hope no one minds me posting this to both CC lists. I just
wanted to pass along the good news - we have updated our eBay auction links,
just point and click for what you're looking for in old computers. Please try
it and we welcome your comments and/or suggestions for making it better and
more complete. Go to:
www.classiccomputing.com/auctions.html
Also, "Classic Computing" #1 is ready to mail! It's turned out great and has
the spirit of it's earlier incarnation, "Historically Brewed." Selected
articles from the new issue, as well as past issues will be added to the site
this week. Thanks very much. Retrocompute!

While we're on the subject of decaying rubber in an HP85, I would add, don't try
to run the printer until you have opened the unit up and freed off the drive
belts - one for paper advance, one for print head. These belts go sticky and
stick to the pulleys, so that when you try and run the machine they tear
themselves to bits.
It's a pity you weren't here a few months ago - a number of us got together and
bought a bulk order of replacement belts very cheaply. I still have a spare
pair if you're desperate, and I imagine one or two others may.
FWIW the teeth on these belts are pitched at 0.080 inch - the standard "mini
pitch", unlike some equipment I have which uses belts with the teeth at 0.081
inch...
Philip.

Hi all,
I'm working on a volunteer project at the Computer History Center to
interface a Documation desk top 80-column card reader to an IBM PC. The
card reader is in very good condition, however we have no documentation
for it. Do you know of, have, or can you provide pointers to any
documentation
for this device, how to interface to it, or operational information?
On the back panel of the reader is a plate which lists the model as
Documation "Model RM/TRM 10.12L-10.12C", with a sticker on the front
with "Model 10.L12+", and operates at 115V 6.1A.
The reader has a 1" x 2" (approximately) data connector on the back with
this layout:
+---------------------+
| O O O O |
| O O O O |
| O O O O O O |
| O O O O |
+ | O X O | +
| O O O O |
| O O O O O O |
| O O O O |
| O O O O |
+---------------------+
Legend: O female connector
X Connector screw hole in center of the recepticle
+ Guide holes where the hood would attach
The data connector is similar to, but isn't, a V.35 connector.
TIA for your help. Please respond via email or phone.
Thanks!

Hi folks,
I went to the Rochester Hamfest on 5 June. Amongst other radio and computer
items I dragged home were two VXT2000 boxes. No displays or keyboards, just
the pizza boxes. The guy literally gave them to me when I was at his
fleamarket space as he was starting to packup and go home just because I
was studying them intently (I never saw one before).
That'll learn me not to stare so dang long at somethin' an' get nabbed by
the owner! My wife was there too. She just rolled her eyes after the
'transaction'. At least she carried the NOS P54 motherboard and parts we
found for my stepson's computer upgrade plus some radio parts and manuals
after I got handed the VXT's.
These I understand are X-terminals but I know nothing else about them.
Searching the usual places for useful info only told me they were X-terms.
Could anybody provide more info to a curious mind as to what the hardware
details are, their typical usage, any other details, etc.? Specific model
numbers are VX20A-AA and VX20A-BC. I see the -AA has color video output and
the -BC is monochrome. Seem to be the only hardware diffs.
Will the good old LK201 keyboard work with these? What about the mono
video: will the VT240 mono monitor work with the -BC?
Kinda classy-lookin' hardware inside. Useful for anything (seriously)?
Off-list please as these are really less than 10 years old.
Thanks in advance for your usual good info!
Regards, Chris

Hi Erik:
Thanks for the email. You'll need the Processor Handbook for the 11/70. It
tells all about how to use the front panel. If you need schematics
(probably not at this stage) then I can assist. I don't have the processor
handbook, I suggest that you post on the classiccmp list and one of
several people (Tony, Megan, Allison, Tim, ...) will likely respond with
an offer to photocopy the relevant sections.
I run a pdp-8 web site, one friend runs a pdp-11 web site on my machine.
He may have posted the 11/70 manual in scanned form, or may have it and be
able to scan it/copy it for you. Check out
http://highgate.comm.sfu.ca/~rcini.
Good luck,
Kevin

Very nice X-Terminal. Even fast. Just got one of these one month ago and
love to have it on my DECStation/NetBSD.
>Could anybody provide more info to a curious mind as to what the hardware

The VXT2000 is a little brother of the VAXStation 4000/90 (got the SGEC
EThernet Chip form there) and the VAXStation 4000/vlc (got the CPU from
there. Same CPU & Clock)

You can use the "standard" ps/2 simms in it. but only the 4MB pieces.
>Will the good old LK201 keyboard work with these?
Yes.
> What about the mono video: will the VT240 mono monitor work with the -BC?
NO, look at the resolution above :-((
>Kinda classy-lookin' hardware inside. Useful for anything (seriously)?
YES. As a X-Terminal.
Have fun,

<Okay Allison, now you caught me with three heretofore unheard of terms:
<Cvax, Nvax and SOC. What the heck are these definitions? My MVII: what ter
<above applies to it?
Microvaxen are all the same like 386, 486, P5, however they mostly differin
technology used to make them.
MVII is the first NMOS version.
Cvax is a CMOS version that was about 2.4-3.0 faster.
SOC is system on chip, more of the glue and larger cache are inside it.
speed on this can run to greater tha 20x MVII.
Nvax is Cvax with internal cache 3-8x MVII
I listed them in order of speed.

Neat little xterms that do DCE, LAT and IP protocals.
<Will the good old LK201 keyboard work with these? What about the mono
LK201 is good, there is a mouse too (round hawly mouse). Monitor is a
VR315. I have one of these. Check to see that there is RAM still in it!
Also the liitle rotary switch sets it for one of many monitors.
<Off-list please as these are really less than 10 years old.
They are close enough to 10 may be even over it.

I finally got all the parts together (including a newly acquired ct-64
terminal) to start the 6800's restoration. I took several pictures that can
