While I agree with you here, I have to admit that, if my PDP-11/70
had switching power supplies, I'd probably run it a lot more often.
I'd *never* make it an irreversible modification, though.
Um. An 11/70 have switched power supplies normally. Did you remove them
and install large transformers? That would become a very heavy machine
in that case. :-)
