MY 8 bit trakball (which I picked up for $8 since they are selling them at
every Kaybee toy store around here for that price) emulates a joystick and
has a 'native' trakball mode.  If one feeds the raw signals to the
appropriate pins on the ST the trakball works like a mouse.  It's much
easier than the Wico trakball conversion.  I'll see if I can come up with
some step by step instructions.
