Folks,
I've determined that the piece of my S/23 that's causing the power
supply to blow its 12V fuse is the machine update card. The manual says
this provides additional R/W storage for microprogram updates. That
sounds like something that wouldn't be necessary for normal operation.
Not knowing anything about this system, but you might check the card for
a bad Tantalum capacitor.
