Macintosh Color Classic “Mystic”


The exterior design of the Color Classic may have been radically different from the original Macintosh but like the 128k, it came with underwhelming performance. In this case due to its low-end 16 MHz Motorola 68030 processor and a maximum of 10 MB RAM.

Enter the hackers. The Macintosh LC575 logic board featured a 33 MHz Motorola 68LC040 processor (upgradeable to a full-68040) and support for up to 68MB RAM. It was also a slot-in replacement for the original Color Classic logic board in what is known as  “Mystic” upgrade.

This machine was originally purchased from MacRenewal then combined with an LC575 I found in a pile of Macintoshes on the side of the highway. It features a Macintosh LC575 logic board, full 33 MHz Motorola 68040 processor, 36 MB RAM, a 4 GB internal hard disk drive, an LC PDS slot ethernet card, an Apple CD600 external SCSI CD-ROM drive and a modified 640x480 resolution monitor. It boots into Mac OS 8.1.
