I'm thinking to the following modification on the cbm 8032 motherboard
reinstall a regulator for 5v  (switched version)
reinstall a 5v regulator in place of 12v (switched version)
Inject +9v DC on the power supply connector for both 5v and 16v... AC

I hope to get:
+5v  normal place
+5v  in place of 12v
nothing on -5v
a bit less than 9v unregulated (for tape)

I did something similar on a tandy coco 2 and it works fine...

any idea ?  (the power supply of the cbm is more complex that the one on 
the coco)...
