finger to keyboard and composed:

There are a couple of transistors, Q701, A1A4M and Q703, N1A4M, which don't register
much of anything on my dvm in the way of a pn-junction. What kind of
transistors are these?

Both are digital transistors with integrated 10K base resistors.

The A1A4M is a 50V, 100mA, NPN type, while the N1A4M is its PNP
complement.

Each transistor has an F,B,A, or G prefix depending on package style.
