It turns out that I was close to the correct answer without knowing it. :-)
The jumpers that I mentioned as being associated with the amount of memory
in the machine are -- but there are two more which control the thick/thin
setting and high res monitor setting. The row of 8 jumpers looks like this:
4 Mb 8 Mb 12 Mb 16 Mb 20 Mb 24 Mb EXTXUR HIGHRES

( MEMORY JUMPERS ) (Net) (Monitor)
If the seventh jumper ("EXTXUR") is in place, then the machine is
configured for Thicknet. Otherwise, it's configured for Thinnet.
These jumpers are located (if you've looking at the board with the
external connectors facing you) to the left of center about 10-12
inches back. They're pretty easy to spot, 'cause they're the only
jumpers back there.
I'd like to thank everyone for their help; the response was overwhelming!
