Hi,

I've been away from my C64 for a few years now, but I'd like to recycle
it and do some hardware hacking.  I'd like to control some DC Lego
motors I have using my C64, and possibly be able to receive sensor
information as well.
 
I presume this should be done over the parallel port.  (Or not?)
Ideally, I'd like to just be able to send/sense logic high and low
signals and let my motor power supply system and sensors handle the
rest.

Any advice or pointers to good documentation?  Or is there something
simple out there I could buy that would do this for me?  

Thanks much!
-Tim
