It was an unencoded (quadrature) mouse. Equivalent to (but not pin-compatible
with) an Amiga mouse, or some flavors of "bus mice".

All of the pre-ADB Apple mice are interchangeable, except that the original
Lisa mice used a strange variant on the DB-9 connector with extra tabs on
the female connector, so later Apple mice will not plug into an early Lisa
unless you hack the connector.
