Well, I've gotten confused enough about the circuit now that I'll only give
what I'm certain about.  And that's not much ;)

(added to the fact that I haven't worked on this since I posted the
message, it's not a pretty sight)

U203 feeds the LCD data lines
U202 controls the contrast of the display through a resistor network. (pins
2-6)
U202-15 connects to RS
U202-9 connects to E
U203's Q'H feeds U202's Serial in

U205 confuses me due to a few pins that look N.C. to me even though they're
inputs, but it's for reading the swithces.

U204 is for turning on LEDs.

counting the blue wire as pin 1 on J2, the purpose of each line is as follows:
1:?
2:serial out
3:?
4:?
5:serial in
6:Vcc
7:Gnd
8:Vo (contrast control)

I found connections on U201 looping back to U201, along with lines on U201
being connected to both the register clock and the serial clock so I'm a
little confused about that one, which is why I haven't succeeded in
finishing the process. (that and I got distracted).
