Subject: CueCat wanted!?!
With the recent talk of CueCat's being used for BarCode scanners, I would
love to get my hands on some of them.
I had one about a year ago, and it worked awesome! Could scan about any type
of BarCode...books, dvd's, cd's. And if you have a database program, such as
DVD Profiler, it works great with it!
Unfortunately my dear beloved granddaughter decided to 'play' with the
CueCat and, sadly, it is no more....
So if anyone has one (or two or three!) either USB or PS2, I would gladly
take it off their hands! Email me and we'll work something out!
Thanks!

Hi
Not sure who posted this part. I doubt they are using a single
zener to regulate 2.5A. Maybe a zener resistor and transistor but
it would be a large zener for that type of current.

Guilty as charged; I can't trace the circuit or read the diode number,
but on closer perusal it is probably a reverse voltage protection diode
across the output, and the 24V is completely unregulated.
And that same closer perusal reveals a few more diodes, so it looks
like a full-wave rectified supply after all.
My point was that it's a really basic linear supply; transformer, 4
diodes and a 2200/35 cap (and that diode and a bleeder resistor).
Incidentally, these printers were also used in a small National
printing calculator, in case you run across one somewhere.

A while ago, I obtained one of these, and have successfully hooked it up to the printer port on (one of) my Linux boxen. It works quite well, and I didn't need to change any software to get it functional. The adapter is housed in a small DB-25 to DB-25 patch box goodie (with the help of a 7400 gate). No problems here (if you desire details, please contact me off list).
My problem is that I don't have a proper chad box for this nice punch. It is a clear plastic box that clips over the front of the punch and holds the chad. My temporary solution is to have a plastic bag with some cable ties to the "exit port". While this "works" it isn't ideal.
So, I'm looking for a chad box for one of these. Any leads would be helpful.
Thanks.

Hi everybody.
I am searching for photos or some information related with the IBM 2970. We
used these devices in the beginning of the 70's but actually there is
nothing available about them here.
Could someone help me with this please ? I would agree it a lot
Kind Regards
Sergio

I don't know where to get one now, but my AIM came packaged with a
steel bottom, a plastic top, and a PSU that has "AIM65" in the part
number and that provides +24V. It looks like many other 1970s
open-frame switchers with a large 1/8" or 3/16" aluminum baseplate and
one or two power transistors, but unlike the others, it has more than
just +5, and +/-12V.
So at one point, someone was making 3"x4"x2" PSUs just for the AIM-65.
Unless you happened to run across some that someone has as a stash of
spares, I don't know where you'd find that exact model now, but it
does exist.

A lot of the old dot matrix printers had +5V and ~+24V supplies that would
work with minor adjustments (also good for 8" floppy drives); they usually
just end up being scrapped anyway.

The Arlington Museum of Information Technology (AMIT) is sponsoring the first annual Vintage
Computer Fair Light - South to be held in conjunction with The 15th annual Antique Science &
Retro-Tech Show And Swap Meet. The combined event will be held Saturday, March 14, 2009 at the
Ramada Hotel, Irving, Texas, 4440 W. Airport Freeway. from 10:00 am to 4:00 pm. Admission is $5.
AMIT Director Gil Carrick said that this combined event should attract many visitors who are
interested in displaying their vintage computing artifacts or in buying, selling, swapping or just
seeing these artifacts. Vintage Computer Fairs have been held in other parts of the country, but
this will be the first one in the South. Since this is the first of these events in the region, it
will not feature any speakers and will only last one day - hence the term "lite."
Antique Science & Retro-Tech Show And Swap Meet organizer Skip Solberg said that for a decade and a
half the event has been a favorite spot for fans of this antique gear to show, sell and swap their
stuff.
Visitors interested in displaying or selling should contact Skip Solberg at 817-467-0368 or email
solberg2 at airmail.net for pricing and availability of table space.
If you'd like more information about the Retro Tech Meet, or to talk with Skip Solberg, please call
817-467-0368, email solberg2 at airmail.net or see the web site at

If you'd like more information about the Vintage Computer Fair, or to talk with Gil Carrick, please
