TI-H: Replacing Capacitorr with Crystal?
I know TI was sloppy in that they didn't use a
crystal, and instead used a capacitor to control the clock speed. Which is
why we can replace C9 (or whatever it is for that calc) with a different value
to get faster/slower speeds. The biggest problem with Clock programs, like
the one I saw on my friend's HP48G, is that clock speed isn't constant, it
varies with battery level.
My question is how difficult would it be to
create an add-on unit that goes in the former C9 connection that would use a
crystal instead of the cap? It would allow for more accurate transmissions
(possibly) and it would allow clock programs. Might even open up the door
to more sound development.
