Re: ADB mouse compatibility on IIgs?

["Bryan Parkoff" <bryan.nospam.parkoff@nospam.com>]

    ADB is like USB however PS/2 is not compatible to ADB using adapter for
Apple IIgs.  The special ADB mouse driver may be needed for GS/OS to
function correctly, but I am not sure where to obtain the driver.  Someone
will try to have the answer as soon as possible.
