[ih] A small story of IMP #1 and the UCLA Computer Club

This is a trivial, and quite irreverent, bit of Internet history....
I, like several others, were members of the UCLA computer club during
the late 1960's. The club's office was in Boelter Hall - not far from
the room that held IMP #1 (and the Sigma computer - along with its
"Sigma EXecutive" documentation, aka "SEX Manuals". My project's
computer, an IBM 7094 - with a true memory leak [the core memory was oil
cooled, and that oil leaked] - was in the next room over and we could
hear the squeals from the AM radio caused by the RF noise from the IMP
and the Sigma.)
Anyway, folks in the Computer Club - especially Mark Kampe - kinda like
to pull pranks. For instance, we would drop things from the top of
Boelter Hall (9 floors up) to see what would happen. The landing zone
was the collection of crunched and bent automobiles resulting from the
early crash-tests of my group, the Institute of Traffic and Traffic
Engineering. We dropped everything from frozen superballs to a lead
container used to hold/transport radioactive materials [it was empty].
There was also a feisty ice-cream vending machine in the hallway that
once-too-often failed to deliver the paid-for frozen treat - so someone
in the club unplugged the machine for a few hours, everything inside
melted, and then plugged it back in, re-frezzing the leaking drippy
mess. That was not nice, but it was - here's a terrible pun - that
vending machine received its just desserts.
Anyway, back to Internet History...
IMP #1 had the rough appearance of an armor plated refrigerator, with
lifting lugs on the top. The machine was "ruggedized".
That word, ruggedized, was like honey to ants - it seriously caught our
attention. So we (I think Mark K. in particular) asked "Is it rugged
enough to survive a drop from the top of Boelter Hall?".
So our imaginations lit up with images of us grabbing IMP #1, hauling it
up to the roof and dropping it into the crashed cars nine floors below.
Obviously, prudence and sanity - and perhaps even some, probably
reluctant, respect for law - prevailed. We never did get beyond the
"what if we did this" stage.
(But a couple of years later some of us migrated from UCLA to SDC in
Santa Monica. At SDC we had an extremely awful HP 2000 minicomputer
that, if I remember properly, did actually suffer such a fate as it was
dropped it from the roof of the Q7A building - three stories tall - onto
the parking lot - a fate that all of us applauded. [It was truly a
terrible machine with an even worse operating system.] Some of use,
years later, moved onto the Interop show nets were we sometime had to
practice the delicate art of percussive maintenance.)
