I've been sifting through the "heap" some more and find I have a couple of
the TI calculators, a '58 and a '59 and a Printer for these two. Does this
sort of thing interest anyone? I bought these when they were the best TI
had to offer, but don't use them much because there's only one functional
(sort-of) battery pack between them.
If you're willing to spring in advance for shipping and maybe some packaging
material, they're yours.

Subject : Commodore wrist watches
Date : Sun, 09 May 1999 21:40:45 -0400
From: Stephanie Chorny <chorny(a)ilap.com>
The Toronto PET Users Group has the opportunity of acquiring a
quantity of Commandeer wrist watches (circa 1980 I believe)- these are
new in the original packaging.
TPUG wishes to make these historic items available to the Commodore
community at a reasonable price (and hopefully not at a loss!). The
purchase price has not yet been determined and the purpose of this
communication is to find out:
a) is there an interest on your part in obtaining this watch?
b) approximately - what is the going price OR what would you pay for a
'mint' Commodore wristwatch?
If you could provide a response to these questions, TPUG will be able
to see if it will be financially feasible to proceed with this
acquisition.
I hope many of you will be able to help TPUG in this decision making
process.
Please reply in this newsgroup or directly to me at chorny(a)ilap.com.
Thanks,
Ernie Chorny, TPUG Board of Directors

Hi Lawrence,
I would like to have one of the CDC Sabre disk drive manuals. My Bull
(Honeywell) machine has some of these, I believe, or at least rather similar
drives.
I could either pick it up mid-June, or else if you would send it my address is
John G. Zabolitzky
Muxelst. 4
81479 Munich
Germany
Of course I am happy to pick up any cost and effort involved!
Regards
John
Hi,
For those of ya'll out there into the really big iron,
I have a few pieces of Univac stuff available:
First is a complete Univac model 1710 key punch machine,
including a manual with schematics etc. I do not know
if it actually works, and would recommend it be checked
out before powering up as it has several motors in it. This is
way too large to ship, though, so if you're interested
you would need to pick it up at my house in central NC.
I can provide digital images of the unit upon request.
Second is a Sperry Univac punched card reader. This
is a desktop-unit, (20"x15"x12") so should be UPS shippable.
I don't have any docs. on it. or any cabling (it has a
"big green connector" on the back). I've taken digital
images already and can provide them upon request.
Third is a Sperry Univac CRT terminal, if there's any
interest in something like this let me know and I'll
get more info. on it.
Fourth is a keyboard from a Univac key punch machine
(probably either a 1610 or 1710). I didn't "trophy"
this myself (as per earlier discussion), the rest of the
machine was already gone. Still, it may be an
interesting relic for those of you who are interested
in 1960's computer stuff.
Those of you who've seen my previous postings know
I'm primarily interested in very early electronic
calculator and certain early microcomputer stuff.
I have a "want" list on my web page, and would consider
trades for some of the items on my list. Recognizing
that not everybody has a stash of old calculators,
I'd consider monetary offers as well, but, please,
>from the U.S. only.
Thanks,

When I have time, I'll dig out my TC02 manual -- I guess the switches will
be similar. I'm still of the opnion this TU03 is Q-bus. Does it have an
empty DIL socket near one of the edge connectors? Does it have a couple of
other switch packs? (I'm wondering how much like my TC02 it is.)

Almost certainly Q-bus, since it's quad-height (all the Unibus Emulex
controllers I've seen are hex), and T means Tape. I'd guess it's a TU10
emulator or similar. What are the connectors like? If it has 2 x 50-way
headers, it'll be a Pertec interface.
BTW, was somebody looking for the Pertec interface pinouts a few days ago?
I found the ASCII and PostScript files if anyone needs them...

975002 looks like an IPI or SMD drive number, but it doesn't quite match
any in my lists. Are there any other numbers? What kind of connectors are

What size are they? Are they 8" or 5.25?
If it is 5.25" (likely) then it looks like it is an
"Elite" class IPI-2 or SMD drive (unclear).
One reference says IPI, another implies SMD.
The nearest equipment # match is for PA4B/F, and this
is an IPI-2, 1.2 gig drive. (ST-41201K).
Hopefully, someone will have more accurate info.

Tried doing that, and it didn't help. It turns out that the C-clip was
vibrating, causing the noise; I should probably have figured that out sooner.
Putting some grease in the groove that the clip fits into solved the problem. I
guess using a hot-melt glue gun would do the job too. (Maybe this info will be
of use to someone in future?)

<that this device can format the disks, not by some special format command

It happens to use a 1773 floppy controller that can format, there is also
local ram and an 8085 micro to make the disk appear smarter.

Between the Disk system with it's 8085 and the DL compatable IO that also
has its own 8085 Plus either 3 ot 6 2651 usarts) it's easy to see how the
system is smarter in some places. for a small system that makes it unique
for it's time.
The same basic bard set was used in the PDT-11/110(MOP loaded) and 11/130
(TU58 tape) the main difference was the use of TU58 (unique with a parallel
interface) and some minor rom level code to boot it.
<I don't know of anything else which ever ran on it... (I would be
<interested to know if there ever was).
I head someone had COS running in it. In theory is a vanilla 11/2 with
28KW of ram and a series of DL ports and a mass storage device that is
sorta RX01(two 256k floppies RX01 format). Unless you used DDCMP to another
system storage would be the limiting aspect.
NOTE: expansion is not possible, there is no externally acccessable bus
or expansion port.
I have the PDT11/130 version and several boards for PDt150/130 as spares.

It's a PDP-11 of the LSI-11 base chipset(no fis but it can be hacked in).

Rt11 most versions. Don't know if there wer others.
The disk system I think is the only RX01 compatable DEC did that could
actually format a blank disk.

There is support for running tasks on PDT's via RSX-11S. While
that's an operating system, it *isn't* a development environment :-).

This is a TC13. A Unibus Pertec-Formatted tape controller,
emulating TS11/TU80.

What sort of connector? If a 60-pin and a 26-pin, then they're SMD.
The "9750" part of the part number sounds like a CDC part number -
Seagate bought out CDC's disk drive business many years ago.
Tim.
In my scrounging trips, I've managed to pick up the following mysteries:
1) A quad-height Qbus?? (Unibus?) Emulex TU03. I first thought this
might be a SCSI controller, but a closer look indicates that it probably
isn't. This board is populated with mostly 14 and 16 pin DIPs, a couple
PALs, 40 pin DIPs, and 28 pin PROMs. My next guess would be a tape
drive interface.....
2) A couple of Seagate hard drives, complete with a power supply on a
mounting channel. These are labelled: Equipment No.: PA4B2A, and on the
drive itself: 975002-001. What are these?? I'm pretty sure there not
SCSI, but other than that, I'm puzzled....

It is a PDP-11, using the LSI-11/2 (and 11/03) chip set. It can have up
to 60kb of user-available memory, a console line (programmed like a DL),
3 other serial lines, an asynch/sync line and a printer port.
The floppy disks are 8" RX01 compatible drives. The interesting thing is
that this device can format the disks, not by some special format command
procedure... it formats a sector when it writes it...
The on-board ROMs know about RT-11 Queue elements, so the RT driver
simply calls the ROM to handle the I/O, and the ROM returns if there
was an error, or when the request is complete.
>Also what OS's run on it? I would guess RT-11 will run on it, but not much
>else.
I don't know of anything else which ever ran on it... (I would be
interested to know if there ever was).
When you put in a PDT-bootable diskette, you type '@@' (two at-signs)
at the console terminal to cause it to boot.
I have heard from some that a version with EIS/FIS is called a
Mini-Minc... I have several PDTs that I have upgraded myself.
Otheriwse, if you locate a EIS/FIS emulator written years ago
by Ian Hammond, you can get EIS/FIS programs to run on it.

Hi again,
More of yesterdays finds. Picked up a pile of AIM 65 computers with the
keyboards and power supplies all mounted on sheets of plywood. I found one
Motorola "Educational Computer" in the pile. It says "Copywrite 1981 by
Motorola, Inc." on it and has a 68000L8 CPU. Unlike the AIMs, it does not
have a display or keyboard. How did you interface to one of these? Does
anyone have the pinouts and/or the instructions for this?
Joe
ARe MINC-11 parts scarce?
Anybody out there with one of these?
