Intel DOES sell the individual dice as keychains. The most beautiful wafers
are the ones that have gone through the gold layer, but I've never seen those
for sale. I seem to recall someone getting one as a plaque for service above
and beyond the call of duty at one point, but that was the only time. Blanks
and old 4 inch wafers used to be for sale at a gem dealer in Los Altos
on San Antonio Road. They had some 4 inch wafers, some 4 inch crystals
, ends of crystals, and so forth.

I'm 15 years old, and even I know that a leaky tube [in a radio] reduces
the sound quality, the loudness (depending if it's an amp tube or not),
reduces the life of the tube, possibly can cause a short in the tube, and
can possibly weaken other components. a leaky tube in a TV will
occasionally cause a bad (or no) picture.
I think the only reason that I know this is that I collect antique radios.
maybe I'm just odd...

Let me know if you are in need of any particular old tubes. I still have a
lot that are new in the original boxes and some more used ones. I just
could not trash them - nostalgia I guess not to mention that they are
getting much more difficult to find. For the hobbyists I would only ask
that you cover the shipping. Commercial use would be different.

heh, that sounds like a cool idea. then you could have fix-it contests similar
to what one car company did. they'd mess something up on several cars and then
teams of young mechanics would race to diagnose and fix the problem first.
just dont forget to make the program windont9x compatible. lol.

well, if you could convince one of those "automatic air freshener"
companies that sell the mist things to make a unit that would give off
"computer smells", you may be in business. just add a solenoid to the top
of each aeresol can topus the button for that particular smell, wire them
into a parallel interface, and you'd be in business.
Just trying to convince them would be the fun part.
Anyway, it's still better when you get to work with the actual equipment,
and having the thrill of finding a 'scope in the trash and fixing it, or
finding scrap parts, throwing something together, and possibly building the
next Cray - complete with 46 K RAM, and a 20 MB HD - all for under $30, and
housed in an old washing machine - also pulled from the curb :^)

I prefer the original systems... The tactile response from an IBM PC
keyboard, the design elegance of an Atari 800, the iterative building of a
screen dump on a HP-85.... this list goes on and on...

Are LED's in TO18 cans with epoxy tops completely gone? I've certainly
seen them used in the past couple years in optical emitter/sensor
combinations.

Emulators are a lot easier to store!

Sorry, this doesn't make it at all... the original poster was talking
about the ability to detach a job from a controlling tty, but having
it continue running. And at a later time, from an entirely different
terminal, allowing the user to reattach that detached job to a new
controlling terminal - in fact, you are given the option of attaching
to the detached job when you log in, so you don't have to log into
a new session, then attach the job.

actually, it was implemented at a lower level - the terminal input
interrupt service.
