Nonetheless, costs for the IBM 5100 “PC” have been nonetheless excessive. Relying on its storage, the costs have been between $8,975 and $19,975.

IBM continued to launch computer systems that have been smaller than the 5100 mannequin over the following a number of years. Nonetheless, they have been all focused at companies and nonetheless have been far dearer than the PCs launched by different firms from the late Seventies into the early Eighties.

In 1980, IBM determined to lastly make a very private pc for each dwelling and workplace use. IBM’s archive site said that the PC’s design was created within the firm’s Boca Raton, Florida workplaces by a small group of 12 folks, led by Invoice Lowe, who was the lab director for these workplaces.
