So it turns out that loose wire-wrap pins seem to be a

11/23's. I just discovered _3_ more on one single 11/23 board - two of them
the pins for the master clock! I put my finger-tip on them and wiggled, and
they were loose.
I've had dozens of those pass through my hands or at least across my
workbench and I don't recall ever seeing that. But given your
experience, it's clearly something to watch for nowadays. I wonder if
it's exacerbated by the wire-wrapping being done.
