Checked it.
-0.60v  There's a Elpac/TDC CB-3811 DC-DC converter on the
 board that may have died.  I'll pull the board tomorrow and test right at
 the legs of the device.  Thanks for questioning whether or not I'd checked
 the -12v supply!
 Finding a replacement is gonna be a stone b*tch I think. :(
 I may have to go to another DC-DC converter that is near the same size
 that I can wire in. 
 Something might be loading it down, too.  I'd check for that before assuming
 it's bad.
 
 I'm not sure I know how to do that.  I was just going to pull the
converter and power it up by itself to see if I get -12v out of it.
