Check out SwissMicros.?ÿ I have the DM42, works like the 42S with more memory, speed, and can download and upload programs.?ÿ
I still use the HP 41cx I purchased fall term my first year at Oregon State.?ÿ It was required for all engineering students and the first intro to engineering for all branches taught programming the beast.?ÿ I did not heart that at the time, HP designed and built them in Corvallis.?ÿ I had a nice 48gx with both the a survey and solar ephemeris card, my crew lost it years ago.?ÿ They had taken it to for a series of solar shots for LiDAR verification and left it on the hood when the drove off.?ÿ I love my 41, I prefer all of the modern features of the 50.?ÿ I recently tried to find a backup and almost fell off my chair when I saw the $500 price tag.
