The System/23 Datamaster (Model 5322 desktop model [2] and Model 5324 floor model [3]) is an 8-bit microcomputer developed by IBM.Released in July 1981, [4] the Datamaster was the least expensive IBM computer until the far less expensive and far more popular IBM PC was announced in the following month.
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 0676 first shipped in November 1982 as a 5247 Disk Storage Unit for the IBM System/23 Datamaster. [67] Developed at the IBM Rochester, Minnesota, laboratory as the 21ED it was an 8-inch HDD with an initial capacity of 15 or 30 MB in two or four 210 mm disks. In 1983 it shipped as the HDD in the 5360 System Unit of the S/36.
It was an 8-bit bus based on the I/O bus of the IBM System/23 Datamaster system - it used the same physical connector, and a similar signal protocol and pinout. [3] A 16-bit version, the IBM AT bus, was introduced with the release of the IBM PC/AT in 1984. The AT bus was a mostly backward-compatible extension of the PC bus—the AT bus ...

The Model F first appeared with the IBM System/23 Datamaster all-in-one computer. It is best known as part of the IBM Personal Computer in 1981 with some keycap label differences, and its subsequent release with the IBM Personal Computer/AT, where it was reconfigured with the AT protocol and some layout revisions.
He worked on the Series/1 system. In 1978 he developed the I/O system for the System/23 Datamaster. In 1980, Bradley was one of twelve engineers developing the first IBM Personal Computer. Bradley developed the ROM BIOS. That got him promoted to manage the BIOS and diagnostics for the IBM PC/XT. In 1983 Bradley formed the Personal Systems ...
The MDA was based on the IBM System/23 Datamaster's display system, [2] and was intended to support business and word processing use with its sharp, high-resolution characters. Each character is rendered in a box of 9 × 14 pixels , of which 7 × 11 depicts the character itself and the other pixels provide space between character columns and lines.
