I've been working on a North Star MDS system for my Sol-20. I have the MDC-A1 controller and the rebadged Shugart SA-400 in the "North Star MICRO-DISK Cabinet (MDS-CAB)".
My drive was set up with the power regulator option to take unregulated +9V and +18V, usually from the power rails of the computer. I've been testing the drive with an external switching supply, and it seems to check out. I don't think the Sol's weaker PSU (compared with an IMSAI other beefier system) would take the additional load very well.
I was curious if anyone out there has an MDS set up with the "North Star Power Supply option (MDS-PS)", which incorporates a transformer, fuse block, switch, etc. in the case?
