Colour Classic


The Apple Macintosh Colour Classic an all-in-one Mac from the early 90ies. Due to its colour display, it is one of the cult Macintoshes. Due to its color capabilities and its tiny all-in-one design, it counts as the predecessor of the iMac. The negative point about the machine is its adressing is limited to 16bit, making 10MB the maximum of RAM even if 12MB sit in the slots. Nowadays, it is hard to imagine that earlier people were doing layout and design stuff on such a tiny 10 inch display.
This ColourClassic was upgraded with an additional board called Presto Plus from Sonnet Technologies. The board features a 68LC040 CPU running @ 66 MHz, additional 32 MB of RAM (Summing up to 32 + 10 = 42 MB) and a 10bT-RJ45 connector for network connectivity without the need for AAUI adapters or SCSI-based network adapters. The board speeds the CC up to unknown levels.
