FS: Fairchild 765H PortaScope Oscilloscope

Vintage 765H PortaScope made by Fairchild / Dummont Labs. Do not have
power cord and no way of testing so being sold strictly AS-IS. I have
no idea if it works? All electronic parts seem to be intact, and the
green hard plastic case in good shape.. handle missing screw on one
side but still functional.

This thing has so many electronics in it, looks like it was part of a
NASA experiment! Or ought to be in a museum! Someone with the knowledge
may be intersted in testing and restoring.

Will sell for best offer. Prefer local pickup in Chapel Hill, NC but
will consider shipping for actual UPS Ground costs + $15 packing
fee..unit probably weighs 50-55 lbs. Please email if
interested in pics, or with offer. Thanks!

Ugh! 50-55 pounds and they called it a portable? heh heh

Actually, something that old probably uses the old 3 pin round plug that
vintage HP equipment also uses.

Which Belden still has in production, and any good wire and cable distributor can sell you. For big bucks. IIRC, Tek
used a standard AC connector back than, and Fairchild often copied the competition products, more likely Tek than HP.
On the other hand, it might have one of those 3 wire small locking AC connectors favored by some manufacturers back then
which really are difficult to find (outside my junk box, anyway).

I have encountered enough equipment that require these strange power
cords (well, strange by today's standards anyway) that I have
constructed a universal power cord for initial power-up of them. It
consists of an AC line cord with the strongest-jawed alligator clips I
could find attached to the end, each covered by sleeves that are 1 or
two sizes too big so the clips are completely covered by the sleeves.
Connect the clips to the power cord posts, making sure that each one is
completely covered by the posts and apply power. Of course, this can't
be used as a permanent cord, but it does allow an easy way to do an
initial test of a status-unknown piece of equipment to see if a hunt for
a difficult-to-find original cord is warranted.

I have discovered that the detachable power cords used on a lot of
vintage test gear are the same ones used on most electromechanical
adding machines of the period. Look for one of those at a flea or thrift
shop if you need a cord like this.

Thank god for PCs.....They are made in such huge numbers that they have
made the standard three-prong power cord used with contemporary test
gear abundant and cheap. Future generations of electronic enthusiasts
will be much less likely to encounter the "wacky cord" problem as a result.
