[sdiy] Fun with LFSRs and such

[Colin Hinz]

A linear feedback shift register (LFSR) can be used as a pseudo-random
noise source, as has been well documented here, there, everywhere.

But it becomes more interesting when it's used as a LF gate, and gets
even more interesting when the taps are chosen with "good" noise
not in mind. Long sequences of '1' or '0' intermingled with bursts
of more random behaviour = golden!

So I present to you a circuit. I've got an LFSR which gates a NAND
synth. Have a look at the schematic:

1980s video arcade.....
