Applications

The Mitsumi KFK-EA4XA is a PS/2 membrane keyboard from the mid-to-late 1990s, designed for AT/PS/2-port desktop computers running Windows 95, Windows 98, and Windows NT-era operating systems. PS/2 keyboards of this generation were standard equipment on virtually every desktop PC sold through the late 1990s and early 2000s, connecting via the 6-pin mini-DIN port found on motherboards of that period. These keyboards remain useful today wherever a PS/2 port is available — including many industrial PCs, older workstations, and servers with native PS/2 connectors — and can also be used on modern systems via a passive PS/2-to-USB adapter. Mitsumi was a well-known OEM keyboard manufacturer supplying major PC brands of the era, and their membrane keyboards were noted for a light, quiet keystroke action typical of the period. The Windows key placement on this board confirms it dates from 1995 or later, when the Windows 95 key was added to the standard 104-key layout.
