The Macintosh PowerBook 1400cs/133 featured a 133 MHz PowerPC 603e processor, 16 MB of RAM, a 1.3 GB hard drive and an 8X CD-ROM drive. The color dual-scan display measured 11.3 inches. The PowerBook 1400cs was similar to the PowerBook 1400c, but the “s” in “cs” indicated a higher quality active-matrix display.
The PowerBook 1400 series was the first PowerBook to use an internal CD-ROM drive and stackable memory modules. This PowerBook also included a clear cover on the outer case and shipped with preprinted “BookCovers” to customize the look of each PowerBook.
