HP/Agilent manuals, several GenRad ones and a few Flukes. Below is the list of
HP
manuals that I've snagged.
I can make these available to anyone,

I love this list! What we find to talk about.
Until about this time last year when I closed the last one, for 11

bottle washer :-)

I've been waiting with baited breath for a GPS watch. NOT a NAVAID on
the wrist but a simple GPS-synced watch. It would seem to me that
making a miniature GPS receiver would be much easier than making a

Hey y'all,
Interesting site but he's kinda behind the times, so to speak :-)
about what modern, more pedestrian watches can do.
Back around Christmas I bought a Luminox dive chronometer, model
