Re: TI-H: re: mouse interface
Well, HP48 has 4 pins... So it probably has I/O for two, and I guess
ground/+v for the other two... I don't know... who knows. Actually A
mouse for a calculator is just like having WinCE for a PDA -- It is
silly. Which is why Palm Pilot is the leader, since it has a nice easy
to use (and upgradable) OS. I personally wouldn't want to sit there
looking at a small screen trying to click on the Start menu...
