Editing Apple Mouse IIc (section)

== Development and Purpose ==

=== Background ===

The Apple IIc, introduced in April 1984, was designed as a compact, portable version of the Apple IIe. Unlike the IIe which required a separate mouse interface card, the IIc featured a built-in dual-purpose port that could accept either a joystick or mouse. This design decision required special consideration for the mouse hardware.

The dual-purpose port presented a technical challenge: the computer needed to distinguish between a joystick and a mouse when either was connected. Apple's solution was to design a mouse with specific identification circuitry that would signal to the IIc what type of device was connected.

=== Design Requirements ===

The IIc mouse needed to:
* Send identification signals to the dual-purpose port
* Maintain compatibility with existing mouse software
* Match the IIc's cream-beige aesthetic
* Provide reliable operation without a dedicated mouse port
* Be manufacturable at reasonable cost
