Oh yeah, I forgot to tell you that Active Surplus does not have any 6522.
I asked last time I went there.

No thank you.

I dunno if I'll be around much.  I might be heading home later.  There are
things at home that I must tend to.

Nooooooooooooooooo.

PS I believe that I'm quite done with all the circuitry.  However, the
range of the IR sensor is rather pathetic @ circa 3ft (I tested in the
dark with 2 OP505s).  I think I might try changing the cap on the IR
emitter so that it emits at a higher frequency.  Maybe 2kHz is too close
to the cutoff frequency of circa 1kHz.  But I think I'll do that on Mon.
