Free I/O Pins on 30b?
Hi, I was wondering how many free I/O (can be configured for input or output) pins I can easily solder to on the HP 30b board? I aquired a few and after making some WP-34s, I'd like to use the rest as general development boards, sort of like arduino is used but with a nice and useful keyboard and display built in and faster processor which can be handy for some projects.

My other idea is to turn them into USB numeric keypads/programable keypads. I purchased one of these ( http://www.amazon.com/HP-Calculators-COM...B002J6BUEI ) thinking HP Calculator, can't go wrong. How wrong I was. Worst HP product I have encountered. Implementing the idea properly out of a 30b seems like a fitting penance for that purchase.
