This 60 page doc covers all three of the 1541 Ultimate units (1541u, 1541u II, 1541u II+).

The Commodore 1351 Mouse is a controller designed for use with the Commodore 64 or Commodore 128 computers.  It features two buttons on the top, and a ball on the underside that is rolled upon a flat surface to manipulate on screen activity.

Basically, this manual is divided into two parts. The first part includes the introduction, mouse cleaning, and tips for general care of the mouse. That part is for the user with mouse-compatible software, who wants simply to plug in the mouse and begin using it. The second part of the manual contains information needed by those who wish to develop software for the mouse.
