Just fyi- in a city telephone exchange there are zillions of gold-plated connector M and F type... The price of connector only is more than 30% of a total exchange...

Agreed. I think "non-volatile configuration bits" would be a good phrase to describe them.
You don't think 'con-fuses' would work just as well? ...

Polarity Insensitive Serial Comms Incidentally, if you're willing to 'hit it hard enough', you can send the power along with the signal. Just put a little AC on as 'line idle', and transform'n'rectify it...
PWM on all pins The LynxMotion SSC-32 runs no less than 32 servos off an ATmega168. It uses some external hardware (look like latches) because there aren't that many pins, and some very...

PAL - a modern equivalent for combinational logic If you really want to demonstrate logic, build a Babbage engine. Static power consumption zero, dynamic power consumption limited by how hard you feel like cranking...

Yup,that's our lesson.

PAL - a modern equivalent for combinational logic Must admit I quit using discrete logic chips (with a few exceptions) in the 16[R/L][2/4/6/8/8] days (before the turn of the century), all in 20-pin DIPs. A 24-pin 22V10 was...
Let me know what a Jubilee looks like when clamped. S.

Imho, edge connectors need gold plating. S.

Morse Code. Send the signal as alternating current - AC, and use OOK signalling. S.
