The IBM Personal Computer

IBM decided to truly compete in the quickly growing low-cost Personal Computer market at the end of 1980. The IBM company established the Entry Systems Division, which was located in Boca Raton, Florida, to develop the new system. The new system division was intentionally located far away from IBM’s main headquarters in New York, or any other IBM facilities, so that it would be able to manage independently as an individual unit. This small group build 12 engineers and designers under the direction of Don Estridge and was charged with developing IBM’s first real personal computer (PC). IBM considered the previous 5100 system, developed in 1975, to be an intelligent programmable terminal more than a genuine computer, even though it truly was a computer. Nearly all these engineers had come to the new system division from the System-23 DataMaster project, which was a small office computer system introduced in 1980 and the direct predecessor of the IBM PC.

Much of the PC’s design was affected by the DataMaster design. In DataMaster’s single-piece architecture, the display and keyboard were integrated into the unit. Because these features were limited, they became external units on the personal computer (PC), although the keyboard layout and electrical diagram were copied from the DataMaster.

Different other parts of the IBM Personal Computer (PC) system also were copied from the DataMaster, including the spread bus or input/output slots, which included not only the same physical 62-pin connector but also almost identical pin featured. This copying of the bus diagram was possible because the personal computer (PC) used the same obstacles controller as the DataMaster and a similar direct memory access (DMA) controller. Also, spread cards already designed for the DataMaster could easily be redesigned to the system on the PC.
