This is _very_ close to what I eventually found at pinouts.com...
NEC 9-pin Multisync:
http://www.pin-outs.com/datasheet_58.htm
IBM 15-pin VGA:
http://www.pin-outs.com/datasheet_15c.html
The difference is that on the NEC 9-pin, 4 and 5 are H. Sync and V. Sync.
>From this information, my adapters are a) identical and b) correct. They
do connect pin 4 on the 9-pin side to pin 13 and pin 5 to pin 14, as one
might expect. The analog wires and associated grounds are as expected.
I guess I'm down to either inverted sync or a defective monitor.
Thanks for the nudge in the right direction.
