Look in the archive. I posted K2 control programs for the HP48 about two years ago.

The original HP-48's (I had a 48SX in college 92-94 before I broke the large display - I was young and 'stupid') have a serial connection. I actually had a simple terminal program running and cluged a serial connection (before I actually bought the official DB9 serial cable) and ran a TNC off of it. To help keep this posting on topic - it is technically feasible to write a program for the 48 series that would allow you to interface with the K2 if you had the time, but with the palm pilots larger display - I would think that the user interface on a Palm would be 10x better (except that graffiti is a poor replacement for a keypad/keyboard). HP left the scientific/graphing calculator scene for a few years and returned with a new model (HP-49/49G+/49GII) that is actually emulating the original 48 processors. Some (all?) of the 49's even have the capability of expanding memory with one of those 512 MB memory cards (which blows the socks off of the original 32KB my 48SX had built in). Here's a few links link to all things relating to HP scientific graphinc calculators: http://www.hpcalc.org http://www.hpmuseum.org/ The major complaints with the newer 49 is that the keys no longer have that solid tactile feel (i.e. it feels cheap). I think they've also pulled the IR port since there was concern about students utilizing that port to cheat during exams. You can still sync up calculators through a wired port. When I recently returned to the college scene - I longed for my old 48 - but ended up buying a TI-89 for my Statistics class (the instructor as well as 99% of the students in the class were 'stuck with' TI's). It did the job well, but it just didn't feel the same - and everytime I pick the thing up now, I still scratch my head trying to figure out how to do some of the simple things I could do very quickly with the 48. (It's sort of like MS Word 2000 - it does too much for you - it kept my decimal inch calculations in fractions for me... but made it difficult to get the whole number with remainder ... a mixed fraction - and since I didn't have time to dig out the manual - I had to do it by hand). Anyhow - in my opinion - HP really has lost its lead in the calculator world in the last 10 years as is evident in the price of their used calculators which are worth their weight in gold. ... after further browsing ... check out this calculator they're developing independent of HP!!! http://www.hpcalc.org/qonos.php If this thing takes off - you'll have linux in the hand - plus a an HP/TI emulator. Read a little further and you'll see that it has an AUDIO I/O port and a SERIAL port... who will be the first to make this thing sing and dance with their K2 and do PSK-31 at the same time?!
