    I was thinking about this the other night {it was a slow night :-)} --
how does the DC option on the PDP-11 work (besides the obvious)? My 11/34
has a DC light on the panel, but I know that my unit did not come with a
battery backup unit.

    What was involved with the DC option? Was it a special PSU and
batteries? Or was it a board and separate UPS?

    Just curious...
