First of all I like to say thank you to the great HP calculator community! I was a little scared before the trip to San Diego - imagine ONE Texas Instruments collector and SIXTY-EIGHT Hewlett Packard fans. But the wonderful event demonstrated easily:
The fans of the HP 35 are like their calculator: Simply perfect!
Thinking about the TI-Nspire on the nice calendar side-by-side with the Casio Classpad 300 and the Xpander prototype convinced me, that I should add them to my Datamath Calculator Museum (www.datamath.org).
I know that there are some Xpander's out. Is there a collector willing to borrow me his working or non-working unit for a week or so? Please remember that I line in the meantime in Rochester, NY.
Thanks in advance for your help.
Regards,
Joerg
