Commodore 64 / 128 - 1351 Mouse Rev B - Pushbutton Switches
ASSY A0101930

Released in 1983, the 1351 Commodore 64 / 128 mouse (originally designed for the Amiga) is a fairly basic, yet very well designed unit.

While extremely similar in design and depending on plug supplied visually identical from the outside the Amiga and 64 version are not compatible with each others system.

The 1351 was released in at least another two variations; one with pushbutton switches (shown below) for the action buttons and one with metal dome switches.

The 1351 supports two modes, a traditional proportional mouse mode and a joystick emulation mode which can be access by holding the right mouse button while turning on the Commodore 64 / 128.

The mouse came boxed with software to update the popular GEOS environment which was crying out for mouse support as well as software and details to help add mouse support to your own programs.

When it was released very few software packages supported the hardware, however the joystick mode enabled early adopters to make use of it surprisingly well. Many art and other creative packages benefited greatly from the mouse in joystick mode.

Like most mice of its era, the unit featured two action buttons and two encoder wheels to dictate X and Y positional movement.
