You are correct; I looked for them before and coudn't find them.  I
looked more carefully today and found them, and, yes, I had my sticks
of RAM in slots 1 and 3. :-/

I also remembered what you said about the -9V line.  I got out my Fluke
and measured between chassis ground and the -9V and -9V return lines.
Each one showed about 1M to ground.  Between the two shows 6.44k.  Each
of those measurements is within measurement error of invariant under
swapping the test leads.  I was hoping they'd show infinity to
everything, including one another, but no such luck.
