These are odds and ends that I've picked up over the years but need information, parts, or something else to make them complete and/or operational.

I'm trying to identify the device that this Nixie tube assembly may have
come from. There are 14 Nixie tubes in each of two display modules.

I have four of these modular power supplies, model number S53P11-1A
made by Fortron/Source. It accepts 120 or 240 volts from a standard IEC
power connector and produces 8.5 volts at nearly 6 amps. It has a female
DB-9 connector coming out of the bottom (top?) of the case.
Does anyone have a pin-out for the output connector?

I have three of these Executone CPU boards, each with a
Rockwell 6504 CPU. As usual, I don't have any documentation
or manuals for these boards, which appear to have come from
some kind of phone system.

This is a model MP-2A (MP-2) made by Tokyo Tatsuno company.
It is some kind of card reader, but I have no documentation
on what type of cards, or what the pin-outs are on the
16-pin dual row connector.

I picked up several electronic lab-type pieces of equipment
recently that were perhaps manufactured by a Chicago company called
Stansi Scientific for use in educational institutions.
I have no other information about them.
These first two devices are pretty straightforward, a decade resistance box and a capacitance box. They appear to be very well made, constructed out of bakelite or a very hard plastic.
Any stories about what these might have been used for? Update: I received the following note from Tom Greenslade, a Professor Emeritus of Physics at Kenyon College in Gambier, Ohio:
The two pieces of apparatus at the bottom of the picture are resistance boxes. When the plug is out, the resistance appears; when the plug is in the resistance is zero.

I'm looking for a manual for this device.
I e-mailed the company that took over the Autogen product line (stoeltingco.com) and received this response: We no longer can provide information or parts on the old Autogen products. All of the manuals and obsolete parts were hauled to the dumpster four years ago. |

This appears to be a "computer-on-a-card" that operates
from an ISA slot. All I have is the card -- no documentation
or manuals.
I've put up a page with several photos and a brief description, which can be seen by clicking here. Any information relating to this board would be greatly appreciated.

I have an Alphasmart Pro with a display problem.

A vertical column of pixels in the third and forth row of
the fifteenth LCD column appear to be out.
Other than that, it's a neat little computer with a socketed ROM for easy updates. |

The only external connection is a 20-wire ribbon cable.

I picked up about a dozen of these "download modules"
at a surplus equipment warehouse. They're manufactured by
Econolite Control Products out of Anaheim, California.

company or these headphones?

kind of eight pin HP-HIL connector.

I have a Grid 2202 Disc Drive. It's black, of course, and
built like a tank. It accepts 5.25 inch floppies. It has
two connectors on the back, each of which can rotate 90
degrees. The connectors themselves are D shell but have
three rows of pins.
The copyright date on the bottom plate is 1982. I don't have the power supply for it. I'd like documentation for this thing, or at least to trade it for something I can use. |
This is a neat little data line monitor build by Hard Engineering
in Huntsville, Alabama (home of NASA's Marshall Space Flight Center and
SCI).
It has a full QWERTY keyboard and a single line LED display, along with a switchable "break-out box" to interconnect the data lines. It is AC powered and comes in a custom carrying case. Although I have the instruction manual, I'd be interested in learning more about the company and other products they might have built. Update: I received the following note:
Just saw your inquiry on the bytebug 625. I actually designed the unit in the early 80's. The unit was upgraded to a bytebug 645 that added T1/ISDN monitoring and Emulation. We sold the company to Tekelec in 1990 and they changed the name to the Chameleon 5. I just moved and threw out all of the old manuals as I was packing. I don't know anyone who supports this product anymore. |
Can anyone identify this?
I picked up this odd box at a thrift shop. It's about seven inches long by four inches wide and three inches high and has a single pushbutton mounted in the top center of the box. A plate on the bottom shows a Model 1628 02 (whatever that is) with a serial number of 7302 and a frequency of B 47, but no manufacturer identification.
UPDATE
In January 2002 I received this e-mail:
Does anyone have more technical information about this setup? |
An answering machine back from the time when Ma Bell
(there was only "The Phone Company" back then) would not
allow anyone to connect anything other than genuine
approved Bell equipment to their lines. (Check the
"Carterphone" decision to see the beginning of the
end of that restriction.)
The sticker on the back says it's a model number 1000TR-05, part number 201722, and is stamped Jun 14 1982. It is supposed to come with some kind of power supply that plugs into a jack at the top, right next to the modular line connector. Any ideas on the specifications (voltage, polarity, amperage) for the external power connection? Even better, does anyone have a manual for this thing? Update: I received an e-mail with the following information:
The power supply is 15 VDC, 500 mA, sleeve positive.

I have three HP ROM drawers that appear to be for the 9835
desktop computer, two with four slots and one with six.
The six-slot drawer is empty, but each of the four-slot drawers
has a ROM in it labeled
Inside the unit is a tuning coil and a trimmer capacitor
feeding a loop antenna.
It has a crystal stamped 27.045 and is powered by a pair of
9 volt batteries.
