I don't know--the funny thing is I work on these things...laugh if you want.
These boards are all-digital and so damn complex I can barely fix them; the
troubleshooting is almost all symptomatic and not logical.

I know what these little signs aren't---they're not test points, they're not
page numbers, they're not coordinates (like p. 6 B3), maybe they're node
numbers?


gimme a circuit full of op-amps and integrators anyday.  even digital pll's.
those I can handle.
