THE IBM MODEL M is a classic. First introduced in 1985, it is the successor to the Model F, which is an equally soughtafter vintage keyboard, if not more so. The Model F had a more difficult layout, but the Model M changed this and became more user-friendly. The Model M helped to create the modernday layout—apart from the lack of Windows keys, it’s the same layout as any other full-size keyboard. It is one of the very first keyboards, if not the first, to include dual Ctrl and Alt keys, function keys, alphanumeric keys, navigation keys, numeric keys, and indicator lights, just like we see today.
