John,

I must be younger than you… I started chip design with 3 micron CMOS back in ‘86. ?

FPGA’s are taking over the world today and even amateur radio as evidenced by the ongoing M17 project. It’s great to be in this field and experience the rapidly growing use of these devices as they replace most, if not all, discrete logic in numerous systems.

More nostalgia!

As a kid I saved my 'chores' earnings to purchase devices like 1N34, 2N107, 2N170 and the venerable CK722.

I remember feeling kind of down when the integrated circuit was developed.

I felt that it would suck the life out of my future designer experience and turn me into a low skill user of canned pre designed P/N's.

Little did I realize at the time how liberating IC devices actually were and how they would transform virtually every aspect of our lives from how we entertain ourselves, to how we do medicine, to how we wage war.

I went on to become a chip designer back in the days of 5 micron NMOS. How far things have come!

One of my dearest possessions is an autographed wafer of TI cellphone chips signed to me by Dr. Jack Kilby,? TI's inventor of the integrated circuit and Nobel Laureate. I will treasure it as long as I live.

My favorite thing about the 2N2222 - easy to remember over decades.

My favorite is the 2n706 and 2n2222, Those were deveeloped and sold back in 1961
and are still available.? In the industry everyone know the 2n2222 as the roach as it
just doesn't die.
