I started that many years ago like 1995ish. I spec'd Tygon (brnad name)
as that was available to me. Most any generic Vinyl tubing works so long
as it fits tight and has enough wall thickness.
After about 10 years it tends to get hard, the fix is obvious.

I have some additional material on the 960 that isn't up yet on
bitsavers. The 960 and 980 share some peripheral interfaces.
Did you end up with the 990 system as well?
[I hope this is on-topic; I believe the machine is at least 20 years old]
I have a NEC Spinwriter 5525 printer that is available for the cost of
shipping (free if you pick it up). The printer is a wide carriage and
appears to have a RS232 serial interface. I do not know if the
printer works or not.
The machine is located in Langdon Alberta Canada (postal code is T0J
1X1) which is approximately 10 minutes east of Calgary.
The machine is rather heavy. I estimate 50 pounds or more. If there
is no interest, the machine is headed to the e-waste recycling.
I can send pictures upon request.

Hello everyone,
I just joined this mailing list today on the advice of more than one vintage
computing contact. I was wondering if anyone could tell me anything about
the Protec Microsystems PRO-83 Z80 Single-Board Computer. I have conducted
an exhaustive search of the Internet and found only two sites (one from a
surplus store and a picture of it from a museum). I would appreciate any
information available, especially information regarding the power supply and
peripheral devices. Thank you very much.
Rob

I have non working 3000/37s with possibly good drives and a 3000 micro GX
that works but has a bad drive. I have tried to boot the micro GX from the
3000-37 drives and get this far.
----------------------------------------
Cold Boot >
HP 32033G.B2.02
Performing a Coldstart
Following Volumes not found
MH7957U1
List Volume tables ?
----------------------------
Seems to freeze after that. It does this on 2 different drives.
Is this even possible to do ???
Does anyone have a OS tape for one of these ??? and which manuals
cover the boot menu and/or startup.
I would like to get both going but the 3000-37's have dead mother boards.
Stan Sieler, are you still around. Seems like every search I do comes up with
your name and advice.
Thanks, Jerry

I have a couple of HPIB cables available at $15 the pair, shipped.
They are:
1 HP10833A ~42"
1 HP92220R ~12"
The 92220R has a right-angle connector at one end and the usual
straight connector at the other. (I wonder if the 'R' indicates
a right hand connector?)
First come, first served.

Hi,
This is a belated response to a post you made here:
http://www.classiccmp.org/pipermail/cctech/2003-February/010641.html I
happened upon it while doing a 'for fun' search on the net for anything
doing with good ol' Century Data, my employer when I was young. Couldn't
resist responding to the post, even if it was half a year late!
The exerciser that you have is/was for the Trident series of hard disk
drives (predecessor to the Marksman). I was the main (in fact, pretty much
the ONLY) technician at Century Data/Calcomp, for these exercisers back from
the late 1970's to the mid 1980's, when they were phased out. I retired in
1985.
Have fun! (BTW, where'd you find one of these dinosaurs??)
Take care,
Nasim
Every so often, a discussion of Tiny BASIC appears around here. I was curious about one of the very first versions of Tiny BASIC, the 8080 implementation done by Whipple and Arnold, as documented in the Vol. 1 No. 1 (Jan 1976) issue of Dr. Dobb's Journal (of Tiny BASIC Calisthenics and Orthodontia)
This issue contains an octal listing of a Tiny BASIC interpreter for the 8080, and I couldn't find this version available for download anywhere. So... I typed it in, and it works!
I documented my work, which is available at
http://oss.readytalk.com/tb/tinybasic.tar.gz
(Note - this location is temporary - I need a home for this if anyone is interested)
Included are the text file for the octal listing, a binary which can be loaded into memory, an attempt to extract the IL from the binary, and some instructions on bringing up Tiny BASIC. I was able to run some simple programs with a Z80 simulator that I've been running, and it appears to work correctly.
I found the PDF of the listing in the ACM digital library:
http://doi.acm.org/10.1145/987491.987494
Typing in octal listings is error-prone enough, and typing them in from bad PDF scans of bad photocopies is even trickier. I have corrected many errors, but I'm sure there are more. If any kind soul would be willing to proofread / correct the listing, it would be **GREATLY** appreciated.
I hope this is of interest to people. I'm very interested in other versions of Tiny BASIC out there, if someone has ever typed this listing before, etc. I'm familiar with Tom Pittman's work, but other resources would be greatly appreciated.

I thought I had posted this, perhaps not.
Anyhow,
I have what's purported to be the "First" computer on the internet,
the one that joined the pieces together and I guess you could say "made" the internet,
or conversely, the "last" node, as it were (depending how you count).
It's also the system where E-Mail was first created.
It's a Sun SLC workstation, owned by Einar Steffard.
I have the original box (very slightly torn),
and the workstation itself is in very good shape except one cosmetic crack, which I believe can be fixed very easily.
I tried the smithsonian, and other computer museums, but basically was told they already had too many of this model,
never mind the significance of this particular unit.
it still runs, last I checked, and has all the original data still intact on it, such as it is.
now, I find myself with a severe lack of space, and need to part with it.
I would like a little bit of money for it, it wasn't a donation to me, and shipping maybe expensive.
or I would be willing to trade it for a vaxstation 4000, or perhaps a 3100 or two.
(I have a need for 2 working vaxen you see)
so anyhow, that's how it is, this piece of history sitting in the corner of my office, collecting dust,
and not doing much else.
I'd like to see it get to a good home, and never scrapped, I think it's too important for that.
so anyhow, anyone who wants this piece of history, drop me a note.
and yes, I have pics (including the shipping labels from Einar to me) for what it's worth...
Dan.
