I think I have a box of unused Sanyo 500-AR cells. If you need some I
could do a quick test and see if any are still good enough to use. The
500-AR are about 1/2 A size. I am sure you can find the dimensions online.

while cheap and easy to injection mold was probably not the best choice for

Its not that they remember their size, it is just that they will get back
to the original tolerances. I imagine if you live someplace where the
humidity is 90+% all the time you won'
experimented with it. I doubt that
it will work but I would love to hear differently. So give it a shot on

trips in them (except for Tesla). Otherwise they make ideal commuter cars
assuming you have a place to charge at home or at work. Cost to operate is
currently 1/5 that of gasoline and when gas goes back up to its record
levels it will be 1/8th the cost.

And the third drive would be rewinding and then unmounted and
changed while the others were actively in service.
The Pertec drive was not a data break device and had to be actively managed
so would not have been able to keep up
with the data stream.

Solder in your feed throughs.
Put the parts on the board.

If on the other hand you want to make even 5 boards you would be better off

For even less power would be to use an Arduino (probably a Due) because
then you are
talking less than 4 watts. This would be about 35 cents per month.
I wouldn't want to run my Straight 8 24x7.and pay the power bill.

The reason to make it glow
dimly when off is to reduce the filament thermal shock when turning on and
off. This makes the bulbs
last a lot longer. The run lamp does not flicker in operation so not
necessary on that one.

. It
was part of a ClassIC which is an 8/a with RX-01 and VT terminal of some
type in a desk with a chair. This one had the daisy wheel printer and a
DECwriter. I have not looked closely at the printer mechanism. The
DECwriter is in pretty bad shape but I have the 8/a and RX-01 running
(mostly). The original desk and chair are going to be refurbished next.
What is the purpose of the query?
