I have a question about the fab process of ICs but really about some
of the terminology.
When I read an article in a EE trade journal and it says a 90nm
process what does that exactly mean? I know about Moore's law and how

I have a display/keypad board from a Brother thermal all-in-one
machine, circa 1995/6 with a chip that I'd love to have identified.
The chip is marked as follows:

Anybody have any idea what the upper frequency limit is on a 2N2222?
Datasheet lists "typical freq (min)" as 200 MHz, but that's all.  Any help
is appreciated...

I'm an engineer student and have the task to research something about
superconducting materials.
I need to know what material has the lowest temperature to get
superconductive...

I have about 2 dozen Beckman Electronic Components Model 6351-92-0 pots.
They are new, in the box but I think they are over 20 years old. Can anyone
enlighten me as to exactly what they are. They turn continuously and very
smoothly. They also have writing on them that says CV 171 ...

Hi to all,
I would like to record tones or simple voice messages on IC's and get
the output through a speaker.
I would be grateful if somebody could help me with the type of IC needed

I have a bad transistor from a Linksys router and am trying to find a
replacement for it and a schematic for the unit if possible.  It's a
basic wired linksys router.  The transistor has the following
markings:

This guy sells components, but why he'd expect to get $2200 for a lame
piece of wood is beyond me.  I guess I'll have to watch it and see what

Anyone know of Newsgroups for selling Electronic repair parts.
Capacitors, IC  etc...
Please Advise via e mail or post?

I have a couple of 'flame effect' neon lamps which intentionally
flicker. Can anyone tell me why and what determines the repetion
rate?
I've put a couple of movies of what I'm talking about at

Ok, so I know a little about electronic devices.  However, I don't
have the parts/spec books memorized like lots of people who do this
stuff all the time. :)
I'm making a device to make my tail lights flash in entertaining

I have a bunch of unknown ICs, would like to know what these two are for
starters (pinouts/data would be great too!)  Both by General Instrument:
AY-5-9100, 18-pin DIP
AY-5-9500, 14-pin DIP

I am trying to specify the connector shown at

to a company in china.  Can anyone help me with a manufacturer,
part number, or even what these things are called?  I have
