Macintosh IIsi

Introduced: October 1990
Terminated: March 1993

Description

The Macintosh IIsi had a Motorola 68030 processor running at 20 MHz.  The 1MB RAM was expandable to 65MB.  It was shipped with either a 40 or 80MB hard drive.  The streamlined case included a 1.44MB floppy drive.  The Macintosh IIsi had a number of ports and was the first Macintosh with built-in sound capabilities. 

As a cheaper version of other computers in the Macintosh II line, some features were limited to cut costs.  There were fewer expansion slots and lesser video capabilities.  The speakers also suffered from some technical problems and were known to fail. 

History

Designed as a cheaper version of the IIci that would be suitable for home use, the Macintosh IIsi was the first Macintosh with built-in sound capabilities, meaning that it could be used to record sound.  Because the pared down machine required less, the Macintosh IIsi could fit into a much smaller case.
