Hi Ben,
 
this can be done pretty straightforward - on the PCB (of the Power One) you can spot (the remains of) two jumpers (VW1 and VW2). "Re-install" them and the supply will provide +- 12V. You may need to adjust the two trimmers (labelled "-V ADJ" and "+V ADJ") to trim to the expected output voltage.

How difficult is it to switch an MOTM 900 over for 12v use? What would this entail?
I'm running my MOTM stuff alongside my Modcan stuff on a giant 3A Cyndustries supply now and want to use the 900 to add a few Doepfer modules. Their cases/supplies are too expen$ive for me so I wanted to build a case and put the 900 back in service.
Also, is there a master list of MOTM current draw per module anywhere I could peruse?
Thanks.
---Ben

The Power One's with added +5V are cheaper than buying 2. Look at the CP-131
model, for example.

But, you can always add a +5V, 6A supply later. Just tied the grounds together
