That'll bring up all the information you could possibly need. Full,
half, quarter, and eighth stepping. Input is "some pulse" which could
be the signal from the parallel port. It also acts as a driver...there
is a higher current version of it, too. A single pulse advances it one
step (or half, quarter, etc) and all the translation is done internally.
Looks like a pretty nice solution, though the form factor could be
troublesome.

I took one look at your name, and immediately thought Ciarcia.
Wow...took me back!
