[sdiy] Another new hard to find part....

[Ray Wilson]

Hi All

I'm using a magnifying lamp to solder regular sized parts now. I guess if
you have the eyes, and the patience for SMT you are good to go for some time
to come.

Serious question though. What function is the 74HC283 (4-bit binary full
adder with fast carry) playing in the sequencer?
