The Mouse 1351 is a mouse made by Commodore in 1986, which can directly be plugged into the 9-pin control port of a C64/128/D/DCR.

The Commodore Mouse 1351 has two buttons on the upper side and a ball on the bottom side. It works in two operating modes: the joystick mode and the proportional mode. The operating mode is decided when the computer is switched on: when the right mouse button is pressed, the mouse goes into the joystick mode, otherwise (default) into the proportional mode.
The "Mouse 1351" contained next to the manual also a Test/Demo-Diskette.
The joystick mode enables the use of the mouse with every joystick-compatible software. It is also provided as a "reserve" for the case when the used software does not support the proportional mode.
The proportional mode needs a special driver program in machine language to unfold its full abilities. Here the mouse works as followed:
1. Every movement is registered inside the mouse. The current position is transfered modulo 64 every 512 micro seconds to the SID registers POTX (for the x-position) and POTY (for the y-position), without the need of software.
Register assignment:
| Bit position | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| POT register | X | P5 | P4 | P3 | P2 | P1 | P0 | N |
wiht:
X ....... bit not used P5-P0 ... mouse position modulo 64 N ....... special (noise) bit
2. The left mouse button is connected as a joystick fire button.
3. The right mouse button is connected to the contact of the upward movement of the joystick.
