  First IBM Clone Motherboard

The ad for the first Colby IBM PC clone Motherboard(1982) This unit started an industry that to this day continues to grow larger every year. Our design was much more integrated than the IBM design. We were able to all put the functions on the motherboard that IBM required the motherboard plus four slots to do to make a working computer. We had everything but the video display driver on the motherboard, so we had four empty slots left for future expansion.

This cover of the magazine showed all the portable computers that were available as of 1982. The only one in that picture that was Microsoft DOS compatible was the Colby. PS-2, as everything else ran CPM. (Compaq was not yet even in business at this time).
