It was interesting to look through the archives. Sad, too. Too many
of those computers are familiar!!
Hey, I probably started way back with a Olivetti Underwood Programma
101 (http://www.silab.it/frox/p101). That was one of my first real
experiences with a programmable computer (some would say calculator),
way back in the early 70's.
Somewhere after that I did some programming on a TRS-80, storing my
programs on audio tape.
And I wish I could use my HP-25 calculator (1976). I need to find
replacement rechargeable batteries. It was amazing what one could
program into that thing with only 49 steps locations! Fun stuff and
RPN was interesting.
Blah, blah, blah. PDP-11, DEC-System 10, Apple II in college... so on.
Anyway, cleaning up through my things I've pretty much decided to break
the ties and offer up a few pieces of equipment, if you know of any
interested parties:
------------------------------------------------------------
SUN 3/160 CPU board (pn 501-1208)
Its a 68020 @ 16.67MHz, 68881, Sun-3 MMU, 4MB, 2 MIPS, 9U VME
format, B/W video, Ethernet, serial, parallel ports. This board weighs
nearly 4 pounds!
The site http://www.sunstuff.org/hardware/systems/sun3/sun3/3-160/
claims this is the first 68020-based Sun machine.
------------------------------------------------------------
>From the same 3/160 machine (which years ago I hauled off the 200 some
pounds of chassis-- don't hate me!)...
Clearpoint SNXRAM Memory Board (dated 1986)
Populated with 8MB with sockets for another 4MB, if you have
the necessary 144 MCM6256 (256K x 1bit) memory chips (with an extra
parity bit for every eight, the numbers work out).
------------------------------------------------------------
Maxtor XT 43805 380MB SCSI Disk
Full Height - Approx 6x8x3 5.5 pounds
------------------------------------------------------------
Micropolis 1325 ST506 85MB SCSI Disk
Full Height - Approx 6x8x3 6 pounds
Dated 1986
------------------------------------------------------------
KIM-1 Microcomputer system (late 70s?)
It's a 6502-based micro. According to
http://www.6502.org/oldmicro/buildkim/kim.htm, "The KIM-1 is the first
computer developed by Commodore, or better, MOS [Technologies]. MOS was
an IC producing factory which Commodore took over to be sure of a
constant supply of ICs.... The KIM-1 has 1152 bytes of RAM, 2048 bytes
of ROM and 30 I/O-lines. Some of these lines are used to drive six
7-segment LED-displays and others are used to read the little
hexadecimal keyboard." You would use audio tape for storage and use a
teletype, etc. for My father built this unit up with more memory, nice
power supply, etc.
------------------------------------------------------------
That's about it (I really don't consider old 386 PCs as interesting),
though I do have a Casio FX-7000 graphing scientific calculator (1985).
But I saw on ebay going for $6. Its not about the money, it just
shows there isn't much interest in it.
Thanks for your time. If you know of anyone interested in these
things, let me know (I may keep the KIM-1).

Greetings,
I am trying to find the 20mA connection diagram for a VT50 terminal. The
VT50 is very similar to the VT52, but has a terminal strip on the underside
of the terminal where the 20mA connection is made. I do not know which
terminal is which. If anyone has a schematic of the VT50, I would very much
like a copy.
Thanks.

It would have been a good buy. With the right adaptor , it can also do
several types of PALs, GALS, and other devices. Sadly, my S3 is rather
more limited. OTOH, it cost less than ?165.

That will certainly do the job.

The OTP package is identical to the ceramic/quartz package, so no problem
there. The HN462532 is pin-compatible to the TMS2532 as well, so that's no
problem either. Both use a single 50ms programing pulse with Vpp=25V.

I'm trying to locate a copy of the instructions for connecting a Model
2000 keyboard to a Model 6000 computer. They were included in the swap
region of one of the boot disks for Xenix 3.2.something. Does anyone have a
copy of this file anywhere?
I think it is called m6010.tar (or something similar).
Any other Tandy Xenix resouces out there?
Thanks,

Hi,
There is a VAXstation II/GPX in a BA23 floorstand available
in the area of Regensburg/Germany.
AFAIR the QBus contains CPU, GPX-Framebuffer, RAM (don't know how much),
ethernet and MFM-controller.
It should be in working condition and is free for pickup (no shipping!).
For further information please contact t.bartzick_NOSPAM_(a)gmx.net
(remove the "_NOSPAM_").

While pawing thru the piles of scrap boards at the local junk emporium,
I came across two identical boards marked "PVK11-G/02". They have the
standard double high/double wide QBUS form factor and dark brown/black
module handles. The only other identification I could find printed on
the boards was "Made in Australia" - no manufacturer or module number.
Each board contains a 6809 (!) chip, an Intel FDC chip, a CRTC chip,
a row of DRAMs, a couple of EPROMS, and some other miscellaneous logic.
Now, of course, the question is "What do I have"??? A quick web search
for PVK11 turned up nothing.
Thanks!

P.S. If you can, please cc me directly with your reply - I read this list
in digest form and I can't wait a whole day to find out!!!

And what do we look like to outsiders when we run
440V Mainframes to do a P200's job? Hopefully
the idea of running such things _full time_ is only
a joke.

Hi.
I've been a little slow in beginning this project, and I apologize to
y'all who have been waiting patiently.
My year-end slam has finally quit, and I have time to play with toys.
I do have Jay West's HP/UX v10.20 media in hand, and will be imaging and
testing copies this week. I have 8xx and 7xx machines available for
verification; anything else is your guess.
I should be able to ship the first week of January.
Jay sent me a list of requests for back-up or replacement media, and
I'll be contacting each of you today or tomorrow off-list. If you had
asked, and don't hear from me by Tuesday, please contact me off-list.
Or, if you need a replacement set of 10.20 media and didn't ask before,
let me know.
This is NOT a warez offer, either on Jay's part or mine. If you ask
for a backup set, I will assume that you have satisfied any licensing
requirements.
I'll be asking for the cost of media & shipping as well - about $2.50
US per CD and about $6 per DDS tape, depending on the current price of
media. There are 8 CDs and 3 4mm DDS tapes. That's based on USPS Media
Mail rates. International or priority may be a little extra.
Please take all further correspondence off-list, so as to keep the
S/N ratio up.
Happy Holidays to everybody!
Doc
For the life of me, I cannot find a good TRSDOS system disk for my TRS-80
M3. Can someone make a copy and send it to me?
If so, please respond to me directly at <sellam(a)vintage.org>.
Thanks!!
Happy Holidays!

If Tony can provide OTPROMs, or you can get EPROMs from BG Micro, my S3
should be able to program them. I can check the Hitachi data sheets to
make sure it uses the correct parameters for OTP devices, in case they're
different from "normal" EPROMs.

Hiho, folks, I have been gone from the list for several months now.
Seems like eternity. All my nice machines are very depressed because
they get no attention. The VAX 11/780 is shivering in the garage, cold
wants to run to warm itself up, but I have not enough time to let it.
I am missing some critical pieces of information, to get it booted and
install BSD on the RA90 disk that I have installed via UDA50.
How do I make myself a boot configuration file that starts the system
>from a newly installed UDA50? Of the boot configs that I have on the
RX01 disk none seems to fit. And I don't know how to show the contents
of these files on the terminal such that I could learn what those boot
commands files do an how to enter them manually. I have no idea where to
put the Unibus address and start address and all that stuff. I'm not
even sure I have set the UBA50's address switches correctly.
I also have installed a second RX01 drive and I was wondering how
I can tell the console to show me a @DIR of that other drive? Is there
a way to switch between the default drive or to give a unit number
to the typical commands (such as @DIR)? My primary goal is to make
copies of some of the more critical RX01 disks that I have, since
some of the disks already have errors on them I don't want to loose
my last console boot disk.
I have asked some of these questions before but got no response, seems
like noone has an 11/780 running. I would really love to get into
touch with some person here who has a VAX11/780 or knows it
so well to can give directions from memory. Aren't there 11/780
people here on the list?
thanks,
-Gunther

Hi folks.
For some time now, Philips has had a mailing list intended for
discussion of their 8051-architecture products. It was very poorly
run, and there were many complaints about slowness, duplicate postings,
etc, but it was a popular list nonetheless. A few days ago, they
announced that they'd be moving the list to a web-based forum, and
everyone screamed. Fortuitously, many weeks prior, I had set up a
mailing list called "microcontrollers" on my mail server, but hadn't
told anyone about it.
Well, you can see where this is going...As expected, Philips' web
forum was dead on arrival, and there are about fifty people (and
counting) on my microcontrollers list. Mine isn't intended to be
8051-specific, but many of the first subscribers were refugees from the
Philips list cutover, so much of the traffic has been 8051-related so
far. I hope for it to be a general (but highly technical) forum for
discussion of topics related to embedded systems development.
Anyway, since I know several of you (especially John Wren, whose name
I see all over the net in 8051 code repositories!) are into embedded
stuff, I thought I'd drop a note to the classiccmp community and let
you know of the list, and invite you to subscribe. It's
microcontrollers(a)neurotica.com, and you can subscribe by pointing a
browser at

I *finally* managed to get probes for my Tektronix 2213 scopes late this
last week. I still can't quite decide which project to tackle first ;P
Unfortunately, most of the P6120 probes are missing the slip-on clip and
ground leads, so I appear to have some more searching ahead of me. Only
one probe has a ground lead, which has obviously been damaged and repaired
by a previous owner. I suspect and hope that the ground leads and clips
will be easier to find than the rest of the probe. Does anyone know
offhand of a source for these parts? I don't expect Tektronix to have the
parts still available, since they told me that they sold off all parts and
spares for the 2213 series to GTE. The last time I talked to someone at
GTE about 2213 parts, they were less than helpful, and suggested I either
send them the scope for repairs (it just needs the plastic front panel) or
go buy a new scope.

Many months ago, due to my frustration trying to find real floppies
to run on my TRS-80's, I began to build a virtual floppy drive for it.
The idea is that I can download software from the Internet (like
Ira's great site) and run it on my TRS-80 without having to make
a floppy.
This little box (the SVD) has an RS232 port on one side, and a TRS-80
floppy edge-card connector on the other. You download a DMK image to
the SVD and the TRS-80 will boot off of it. You can use the standard
TRS-80 DOS tools then to make a copy of the disk...or whatever.
The box is in pretty good shape now, but still not fully functional.
You can boot most OS's and even many copy-protected disks. You can't,
though, write to the SVD from the TRS-80.
I'm looking to make this box available for all TRS-80 nuts. I
don't want to make any money off of it, but would like to use any
profits (beyond cost of parts) to fund sites like Ira's or other
vintage computer concerns. And the more people who will buy it,
the cheaper the cost of parts. I'm guessing that I can get the
cost of the box down to $50 for parts, so I'm thinking that a $75
price tag would work.
Soooo, I'm looking for one or two beta testers to help me make sure
that I've covered all of my bases, as well as to help move the SVD
forward. I need help in testing, but also writing useful software
for Linux and Windows to manage the download to the SVD. Also, I'm
going to need help figuring out the copy-protection of some disks.
Any volunteers out there? For more information, check out the
beginnings of the SVD web-site: http://www.rothfus.com/SVD .
Or just e-mail me eric(a)rothfus.com.
Thanks!

Does anyone have a working boot disk for a Sharp MZ-80B?
I went to use mine for the first time in a few months, and all of the disks
are either reporting "Not a Master" or "Read Error". Since I *know* that at
least 3 /should/ be bootable[1], there is clearly something awry with
either the disks or drives. I'm going to try my spare set of drives
tomorrow, but if that doesn't work then I'm stuck :(
TIA
[1] One of them I made myself, used it, and even labelled it "80B Boot
Disk". And that reports "Not a master" now. Grrrr. :(
