Cruel? Sorry, didn't mean to be. Speaking if cruel, the person who
sold me one PERQ made me take another as a condition for being able to
buy a PERQ... life's so unfair, isn't it? Just think of the
difficulty I had driving home with two PERQ-T2 chasis, a 19" landscape
monitor and a keyboard in the back of the station wagon - it wasn't
easy to see out of the tailgate window. As to my PERQ-1A systems, the
shipping cost for them was rather cruel, and, alas, neither one is
presently running. Does anyone know where I can obtain one or more
spare SA4008 hard drives to get these PERQs running again?

BTW, if anyone's interested, before the page goes away, grab a copy of

before it goes away. It looks like a good minimal, reference for some
larger, older, drives, even though it's lacking some useful details.
BTW, I checked there a while back trying to find one of these drives,
and was told that they don't deal with them any longer.

Thanks for the offer. Alas, I must reject it - no trade... well, of
course, if you toss in a complete PDP-11/45, a Data General Eclipse
system running AOS/VS, a VAX 11/730, a pair of McIntosh MC-2000 tube
(valve) amps, and some body parts that I can't find for my car (just
because it's 29 years old is no reason for the manufacture of the
parts to have been discontinued!), and a house on a couple of dozen
acres of good, partially wooded, farm/pasture land in an area that I
like - with good well water or city water, then we can talk about a
trade for a working PERQ with lots of neat software, copies of the
schematics, hundreds of pages of PERQ-related e-mail, and copies of
other neat PERQ-relted things. See, I'm a very reasonable man who's
always willing to accept a good deal. ;-)

That sounds like a fun toy!
