Sure you could make a scope out of it, you'd just be doing a plot of an
input
signal. The problem is the sampling speed, you'd have to have an analog to
digital converter on the probe (and software to do TI Protocol), then send
the
data into the calc on the link port, so the link port speed is going to be
your
limiting factor. I don't recall what speed the link port can run at, but if
you used
8 bit samples you could probably do a 1-2kHz scope without too much trouble.
Maybe you could put an AVR or some other microcontroller on the link port
to do the data capture at a higher sample rate, then transfer the data to
the
calculator for viewing.
