Re: Kensington Turbo Mouse manual

The one that can connect to the mouse card is styled after the
original Mac keyboard - and has visible rises where the optical wheels
are, protruding on the top slightly.

The other 9 pin one is serial for x86 hardware, and the cable detaches
from it like the ADB models.

None of them are interchangeable except that the x86 one, some models
can be used on either PS/2 or serial depending on available
connectors.

The device was originally marketed by a company called Assimilation
Process as the trackball that was styled after the Mac 128/512
keyboard - and Kensington absorbed them about the time of the Mac Plus.
