Editing IBM System/23 Datamaster (section)

==Influence on later IBM systems==
The familiarity the design group gained on the Datamaster project encouraged selection of an Intel CPU for the IBM PC. The delay caused by the decision to reuse [[IBM System/34|System/34]] BASIC in the Datamaster was one of the factors in IBM's selection of [[Microsoft BASIC]] for the PC (the other being the popularity of Microsoft BASIC on home computers at the time).{{r|bradley199009}}

A number of hardware components from the Datamaster were reused in the later [[IBM Personal Computer|IBM PC]].<ref name="bradley199009" /> The PC's expansion bus, later known as the [[Industry Standard Architecture|ISA bus]], was based on the Datamaster's I/O bus.<ref>{{cite web|url=https://www.edn.com/whence-came-the-ibm-pc/|title=Whence Came the IBM PC|website=edn.com|date=2001-09-15|access-date=2020-10-13|author=John Titus}}</ref> The Datamaster's [[Model F keyboard]] with its [[IBM 5250|5251]]-style key arrangement was also reused in the PC, albeit with a serial interface (instead of the parallel one used on the Datamaster) and a new external housing.{{r|bradley199009}}
