Keyboards

Windows 1.0 supported standard IBM PC and AT keyboards, as well as some non-standard OEM keyboards, like the ones used with non-PC compatible machines that ran Windows (e.g. Apricot XEN). The only supported layout in the retail PC release of version 1.01 was US English QWERTY, though some OEMs (like Zenith and Tulip) decided to include additional non-English layouts. These became standard in the retail release of version 1.02 and continued to be included with later versions and OEM releases.
