In addition to building the first commercial portable Mac, the WalkMac, Chuck Colby also developed the first Mac tablet, which he called the Colby Classmate™ Portable Computer. It was introduced at the August 1991 Macworld Expo in Boston.
The Classmate is built around a Mac Classic logic board. It has a built-in trackball and membrane keyboard, setting it apart from every other Mac clone. You could buy the Classmate preassembled for $2,999 or have your dealer order a $1,599 kit into which you could transplant the logic board from a Mac Classic – or you could send your Classic logic board to Colby for installation at the same $1,599 price.
Because the Classic can accept a Classic II logic board, it should be easy to upgrade the Classmate to a 16 MHz 68030.
