The Intel 8008-based Micral N, the first personal computer using a microprocessor, is offered for sale. Each diskette can hold as much data as 3,000 standard 80-column punched cards. It uses IBM's first read/write diskette, a single-sided 8-inch-diameter " memory disk"-a new recording medium to replace punched cards. IBM introduces the IBM 3740 data entry system. Intel claims its first two microcomputers command about 99% of the market which Fairchild Semiconductor, National Semiconductor and Rockwell International have joined. It can be programmed in two minutes using Intel's punched paper tape-actuated programmer, and erased as often as needed by shining an ultraviolet light through a transparent quartz cap on the package. Intel introduces the 2048- bit (256- byte) erasable 1702A EPROM chip. Intel's support for system-building includes SIM4-01 and SIM8-01 prototyping boards that form functioning micro computers, programmable read-only memory (PROM) programmers, and a PROM-based assembler. Microcomputers are increasingly used in systems too small or slow to warrant use of minicomputers.
Some 200 Intel customers have used the MCS-4 and MCS-8 microcomputer chip sets introduced in 19 in more than 60 applications, including: point-of-sale terminals typewriter-sized general-purpose data processing machines that tabulate accounts, type invoices, and write checks and personalized form letters process controllers for automatic bottle-loading machines and a front-end processor in a dial-up communications controller.

End-user retail – all versions of IBM PC DOS (and other OEM-adapted versions) were sold to end users.Shrink wrap packaged product for smaller OEMs ( system builders) – starting with MS-DOS 3.2 in 1986, Microsoft offered these in addition to OAKs.OEM adaptation kits (OAKs) – all Microsoft releases before version 3.2 were OAKs only.Non-x86 operating systems named "DOS" are not part of the scope of this timeline.Īlso presented is a timeline of events in the history of the 8-bit 8080-based and 16-bit x86-based CP/M operating systems from 1974 to 2014, as well as the hardware and software developments from 1973 to 1995 which formed the foundation for the initial version and subsequent enhanced versions of these operating systems. This article presents a timeline of events in the history of 16-bit x86 DOS-family disk operating systems from 1980 to present.
