I have a couple of HPIB cables available at $15 the pair, shipped.
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.
This is a belated response to a post you made here:
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
Have fun! (BTW, where'd you find one of these dinosaurs??)
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
(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:
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.
Don't pick lemons.

I thought I had posted this, perhaps not.
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...

Subject: Looking for : Sharp PC-1405
Or equiv (Tandy had them as PC-2 or something, iirc).
The goal of my classic collection is to get one of every computer I've
programmed over the years. One of the first computers I programmed was a
PC-1405 (actually, I can't remember the exact model).
I found one of these in a pawn shop. By brother "stole" it. I found
another. This was my one classic computer that was helluva useful. So
useful I took it with my places. And, well, I've just lost it. I've
checked eBay and there are a few Sharp Pocket Computers, but W@W L@@K @
T3H PR1C3Z! Buy it now for "only" 300 USD!
So, does anyone here have one they don't need and/or would be willing to
let go for a reasonable price?
I've got a PC-1421 Financial Computer if you (or anybody) are interested:
76 character keyboard
16 character display
40K ROM Basic
4.2 Kb RAM
Interface for optional CE-126 Printer/Cassette (don't have)
Basic program mode
Basic run mode
Almost new, in box with cover & 280P manual. Make me an offer (less than
US$ 300, or even CDN$ 300 :).
The 8/L, ASR33, DF32 disk emulator project has been sold. Thanks
for all your interest (and offers). Anyone who wants the DF32
emulator schematic and artwork, I can email you a copy. I hope
someone can take my "first draft" and make a useful unit for those
who are interested.
I have a working ADM-3A that I may want to sell also. It has a
homebrewed lower-case 2716 ROM (thanks Steve Loboyko for the font
files). I installed the "optional" parts for current loop on the
main PCB, and used it with the 8/L. The only thing that's missing
is the little aluminum panel covering the dip switches.
Any interest? Same deal as before, please email offers, "sealed
I have an Atari 800xl and a couple of 1050 disk drives. I also have
two copies of the M.U.L.E. game on disk. Unfortunately, I can't get
either to boot on the 800xl. I suspect that these are older games that
were written for the 400/800 and may need the "translator disk" that
allowed the 800xl to run games written for the older machines. Does
anyone know where I could obtain a copy of this translator disk?
I have a fine old Stag PPZ modular EPROM programmer:
It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called
Z-modules by Stag. I've recently acquired a new module, Zm3000, which
looks like a more recent EPROM module. The chips in the Zm3000 are
date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main
unit contains a 6809 CPU and a small CRT display.
Does anyone know anything about this system? What about other Z-module
types? In particular, should the Zm3000 work with the PPZ, because I
currently get an error message "Incorrect Mainframe"?
Thanks in advance for any clues! (Virtually all I get from Google is a
link back to my own web page!)
