	The 11/20 used a switch mode power supply (H720) (I still have a
functional machine!). You would have to go back to something like a PDP8/e
(got one of these two!) for a huge linear power supply. It has a huge SCR for
the overvoltage crowbar in order to dump all the energy in the filter capacitors
