No, it's SPC; other sources, e.g.
So if you have a DD11-B, you must have a BA11-D, with the 9-pin power
The best thing to do is get a DD11-C or -D, and build an adapter cable to go
from a 9-pin male (shell; female pins) to a 15-pin female (shell; male pins),
so you don't have to mess with the harness. Part numbers here:
Then you can plug in any memory you've got the right voltages for; the MS11-E
takes + and -15V (in addition to +5V, of course).
