Thanks to all thow responded - and for the excellent descriptions
of how it all works.
After experiementing with a load, I decided that it looked good enough
to try at full power, and did so with no problems - the transformer
buzzes more loudly than a standard one, however I am told that this
is normal for a C.V. unit.
Playing with the Variac, I confirmed that the power supply truly does
provide superior line regulation - from 90v to 120v, the output of the
supply is pretty constant at about 9v, and barely changes. It is also
much more stable with changes in the load than a standard supply.
Regards,
Dave

Hey, that cyclonic storm was NOT MY idea!

Thud! sound of body hitting floor.

I found the professor that used to use this old HP-2116A. He had a few
things around from back then. I picked up a couple pocket manuals:
* hp-2116a computer "micromanual" central processor
* hp 21mx microprogramming pocket guide
and 4 paper tapes:
* hand labeled "block loader" with instructions
* 24307-16001 rev 1419 DOS III B system generator program (large)
* 24127-60001 rev a 16k sio teleprinter driver - ipl compati
* hand labeled - non eau-lib 24146a (large)
I've not gotten around to working on the tape reader, so just posting in
case there's something someone has been searching for.
Oh, and Jay isn't on irc at the moment or I'd ask him. ;-)
#classiccmp on irc.freenode.net
still having fun. ;-)

An amazing site; thanks for posting it! According to this site, they are
called Minitrons and they even had the datasheet for them. Thanks!!!

I was hoping to tap in to the combined expertise here
to settle a question.
Let's say that tomorrow, and EMP weapon is employed
over a major city in this country.
Is there anything an average citizen can do to protect
their Computers (Classic or otherwise)?
Would having them unplugged help?
Or must they be shielded in some way?
Regards,
Al
