PS: I forgot to mention: that board, IIRC, _has_ to go into a Modified UNIBUS
slot. Plugging it into something that's _not_ MUD will, I am pretty sure, fry
something. Do you have a backplane with has MUD slots to plug it into? I
_think_ DD11-C's and DD11-D's have them.

I'm clearly a little slow this morning: why can't you use a 'scope on it?

In the US, 'vanilla' 75W bulbs are now also banned (and I think 60W's are
headed that way, too); 'specialty' bulbs (not sure of the exact definition -
think coloured, etc) of 75W and 100W are still allowed. (As are, ironically,
plain 150W and 200W!)
