Hmm... Doesn't think this is a computer, eh? Wonder what it *is* then? It
calculates, and provides a results of those calculations into some kind of
output -- usually on paper. Actually, there's an even older, wooden
computer that provided a visual output. What was it? (Is this OT? Both
units compute, and are over 10 years old...)

Damm! Now there's something that you don't see everyday!

Calling an Enigma a computer is really stretching the definition. They
are incredibly simple machines - the internal circuitry consists of not
much more than a battery, wires, the wheels (fancy rotary switches,
basically), a plugboard, and a bunch of lightbulbs.
For a previous question - the number of Enigmas in private hands is well
over 100 units. They are really not all that rare, but the price ($20,000
is not unusual) is high because of the extreme demand.
It is the U.S. crypto gear that is truely rare...

Well, as far as it goes, a computer needs to be able to:
a) have a stored (changeable) programm
b) execute instructions conditionaly
c) do a loop
sometimes also cited:
d) a way for input/output
of these basics, the Enigma is only good for the first one,
since the wheels can be seen as the programm, and they where
changeable. None of the other two conditions are met, since
there is no loop and no conditional operations ... well, ok,
one may see the repetive execution of the ecryption programm
as a loop, but then the conditional execution is still missing.

There's a fellow here on the east coast that actually let me touch his
enigma. I hesitate to say "play with", no way I wanted to get into a
you-break-t-you-bought-it situation. I believe he's reachable at the
TCF and at www.w1tp.com
I think he had a $20K pricetag on it BTW
Here's a nice page about enigmas, Dayton and w1tp.

Does that include my AN/UYK-20S and UYK-44s? I'd happily trade them for an Enigma
:-)
