NEC PowerMate 286 power connector ?

I have to rerpair an old NEC PowerMate 286 wih broken power supply.
The ps is a TDK PU607.
I learned that there are 2 type of connectors on the market, an ATX 20
pin and an AT 6+6 pins.
Bur the NEC has a 9-pin and a 3- pin connector. No chance to get the
info from TDK nor NEC.

Colors from front to back:
br, br, bk then bk, bk, or, or, bk, bk, red, red,red (or=orange,
bk=black, br=brown)

All reds and all sw are connected in the supply (< 0.3 Ohms), while
browns are not connected.
Reds are probably +5V and orange are + 12 because the are connected to
the 4 pin hard disk power connector.

Any hints where -5 and -12V is ?

Thanks, Dieter

Locate the -5V and -12V rails at the ISA slots and test for continuity
with the power connector:
