The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.
The engineering prototype and design model were utilized internally by Lowe in his early efforts to demonstrate the viability of creating a single-user computer. Throughout the 1970s he continually demonstrated numerous single-user computer design concepts in an effort to convince IBM to enter the personal computer business.
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers at International Business Machines (IBM), directed by William C. Lowe and ...
Model 20 disk storage uses IBM 2311 disk drives, model 11 or 12, attached to an integrated "storage control feature" on the CPU. [1]: pp.58–76 If multiple drives are attached they have to be the same model. Both models use the 1316 disk pack which provides a maximum of 203 cylinders with 10 tracks per cylinder. The model 11 uses all cylinders ...
EduQuest's first computer system was the PS/2 Model 25 SX, an update to the Model 25 all-in-one offering within IBM's PS/2 line of personal computers that upgraded the processor to an i386SX. [11] The PS/2 Model 25 SX was developed shortly before the formation of EduQuest, in IBM's Boca Raton facility, led by José García. [12]
Mark E. Dean (born March 2, 1957) [1] is an American inventor and computer engineer. He developed the ISA bus with his partner Dennis Moeller, and he led a design team for making a one-gigahertz computer processor chip. [2] He holds three of nine PC patents for being the co-creator of the IBM personal computer released in 1981. [3]
Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system.
CDP advertisements stated that the MPC "can use software and hardware originally intended for the IBM Personal Computer". [4] The "Multi" in its name hinted to the fact that it could also run the multi-user operating system MP/M-86. [5] The MPC was the first IBM PC clone and was actually superior to the IBM original. It came with 128 KB RAM ...
