This is a PS/2 to Atari ST-class mouse adapter.

Enables any PS/2 mouse to work with your Atari ST, STE, Mega, Mega STE, TT030, or Falcon.  Works best with ball mice, but works with optical mice too.  Doesn't like mouse acceleration applications or when you move the mouse super fast (faster than you'd ever need to use it).  Don't plug or unplug it while the machine is turned on or it could become damaged.

Shipped promptly via USPS Ground Advantage.  Surcharge for USPS Priority Mail shipping.

No returns or technical support.
