Here's a line of ADF scanners that seem pretty reasonably priced with
decent performance and specs:

Hi
There was a talk at our last svfig ( Silicon Valley Forth Interest Group )
about how to find the interesting integer ratios ( like 355/113 ). Although,
one can simply try all kinds of numbers ( quite quick on todays processors ),
there are algorithms based on number theory that are faster. I wish I was
paying more attention so I could pass on what was done.
The talk was based on creating speciallized languages to handle these
interesting problems of LSD's ( Least Common Denominator ). The fellow
that gave the talk was named LaFarr. Forth is especially adapt at
creating application oriented languages. I fact that is the way
one normally programs in Forth, once they know what they are doing.

I'm sure the kit I bought was from Kensington.
I know they sell (or sold) these kits, and have (had) ones for the
Powerbooks. For those it was a little cynlinder with a finger on the end.
You slipped the finger into the security hole, then when you turned the
key, it spun the finger behind the plastic of the case, latching the
cylinder to the powerbook. Then the cable would be fed thru the cylinder
(or was maybe preattached, I don't recall), and the cable was secured to
some other item to keep it from being moved (desk, cinderblock, really
really big dog...)
I also recall a different laptop security product. It was a stick on
alarm that was motion sensitive. It had a keypad on the top to type in
your code to deactivate it. The idea was it glued to the powerbook, so
you could put the powerbook down on a desk, turn the alarm on, and walk
away. If anyone moved or touched the powerbook, the alarm would go off.
I'm not sure how much use it was. If you could run fast, you could still
steal it since it wasn't fixed to any object. You would just run with it
beeping (stuff it in a bag full of rags and it would probably silence
enough to be able to hide it until the battery died, or you could pry it
off the powerbook).
I'm pretty sure these only came in a glue on design, and I'm not sure
when I first saw one, they might have been after the Portable was
retired. So if you need something that is specific to the Portable's
security hole, then that didn't help you (but it was a fun read anyway).

Hi! do you still have this for sale? And do you have the controller card for it too?
Thanks, John

I've never seen them for VCRs before, but it doesn't surprise me. I have
seen recently similar alarms that you can put on furniture or other items
you don't want a pet on, and when it is jiggled or otherwise detects the
pet (I think some are infrared detectors), the alarm goes off briefly.
I did like the one I saw that was an electric pad. When the pet climbs on
the pad, their weight activates it and they get a shock. I'm sure its
harmless, but I'm not sure I would want to go shocking my cat on a
regular basis (but I have thought about doing the same thing with the
screen top to my lizard tank that my cat keeps climbing on and then
falling thru).

>cost ?400 (US$700) and not the ?29 (US$49) I've seen them recently...
I just paid US $14 for a DVD player for my father for Xmas. He's been
complaining he wants one, but I know it won't ever be turned on... so I
bought one that was on sale, had a $10 rebate, and I used "Best Buy
Bucks" from a McDonalds promotion that I had saved up. When I was done,
total cost was $14. (and they asked if I wanted the $30 extended warranty
on it!!!)
A bit of a price difference from my first DVD player that cost me $500.
Of course, I also suspect that my first player will be running happily
years from now, when the $14 model has long since died.

Can you let me know whether you still have OMTI7250 controller board as I am trying to repair an older version the OMTI 5200.
