[time-nuts] Where does the VXI E1740A fit in ?

[Pete Lancashire]

I pretty much agree. Toss in so many companies trashed the originals
and you are left with luck that someone took a copy home with them.

I'll toss in another one, you get a surplus dealer and he immediately
breaks up a 'system' up to in his mind make more money and many times
that corrugated box with papers floppies etc gets tossed out or a couple
times I've witnessed when I use to go to industrial auctions tossed in
the dumpster  as his is loading his hoard. I made it a point to be around
after everyone has loaded up. Got many a manual, attenuator, scope probe,
etc that way.

The same goes for what HP/Agilent calls CLIPS, or what should be called
real service manual.

After say 1990 all this stuff was on a disk drive somewhere, and should
have been copied to at least a ftp site. Even drawings and manuals could
be eventually recreated.

It actually surprises me the of all companies HP/Agilent does not have all
documentation say after 1990 available.
