The Macintosh 128K introduced the Compact Macintosh case style. The bevelled edges were also used on Apple's other products of the time like the Apple II series and the Apple III
Compact Macintosh and Classic Macintosh[1] are informal terms that refer to the direct descendants of the original Macintosh personal computer case design by Apple Computer, Inc. All of them are all-in-one desktop computer designs with the display integrated in the computer case, but not the keyboard. These terms are only used for the models using the case style of the original Macintosh sold between 1984 and the mid-1990s — later, larger all-in-one models like the Macintosh LC 500 series, the Macintosh Performa 5xxx series or the iMac are not usually called "Compact" and definitely not "Classic". The Apple Lisa-derived Macintosh XL is a borderline case, and is included by Apple in their "Classic" spec page, but not counted among the Compact range by others.
^ The name "Classic Macintosh" is widespread, but somewhat confusing because some (but not all) specific models in the series were called "Macintosh Classic", and also because of the "Classic" software environment in Mac OS X.
