Yes, I do.  I&#x27;d have to dig them up but I remember a mechanical design module as well as an electrical design module.<p>You could also plug in other things into those ports.  I have a magnetic card reader that was used to save and load your programs.  There&#x27;s also a little printer and an expanded I&#x2F;O interface.  I haven&#x27;t looked at some of this stuff in years.
