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.
