The
Macintosh IIsi is an
Apple Macintosh model in the
Macintosh II series produced from 1990 to 1993. Announced at the same time as the
Macintosh LC, the IIsi was the first Macintosh to ship with built-in sound-in capabilities. The LC also had a sound-in port but did not ship until later. It was introduced as a low-cost alternative to the professional desktop models for home use, but offered more features and performance than the
LC series. It had color and could drive a number of different 12"-14" Apple monitors, with a maximum screen resolution of 640×480 in eight-bit color.
