In order, I like my HP15C, HP11C, and way behind HP48SX. And then there
is my HP25.

I originally purchased an HP35, then an HP45


Hi Tom,

A Rockwell (model unknown) was first in 1974. It was followed by an
HP16C (software oriented - lots of bits resolution). The Rockwell
was replaced by an HP20S. EasyCalc 1.22 for the Palm Tungsten
(shareware) - it does both scientific and bit logic.

The Palm is closest to me (naturally), the HP20S is under the display
here; the 16C is in the office (had to get up and toggle the power to
see if the second set of batteries still held a charge, they do -
after a thump or two to wake them up).
