, thus it is only compatible with the C64/C128 and will not work on the VIC-20 despite using the same 9-pin connector. An Amiga mouse, although electrically compatible with the C64, uses the paddle registers and will be much more CPU-intensive to read than the 1351. A few programs such as Interpaint support Amiga mice. The mouse was distributed with a user manual containing maintenance instructions,

Reception

The 1351 was favorably reviewed by '' The Transactor'', which praised the unit's ergonomic design and tactile feedback and the quality of the accompanying documentation. The reviewer noted that, at the time of writing, very little commercial software supported the 1351 in proportional mode, but suggested that the mouse would be of benefit in joystick mode in drawing programs, font and sprite editors, and certain kinds of games. Software that can use a 1351 mouse includes GEOS, '' The Faery Tale Adventure'', '' Operation Wolf'', and assorted application/drawing programs.
