Specifications & What's Included Model: 5140, Revision H01-A Key count: 104 keys, full-size layout Connector: 5-pin DIN (AT interface) Cable: Coiled, attached FCC ID: E5XKBM10410 Country of manufacture: China Complies with FCC Part 15 Class B and Canadian ICES-003 Class B Applications AT-style keyboards with 5-pin DIN connectors were the standard input device for IBM PC AT and compatible desktop computers throughout the mid-1980s to early 1990s. They were used with a wide range of DOS-based machines from manufacturers such as IBM, Compaq, Tandy, and numerous clone builders. The 5-pin DIN connector was the dominant keyboard interface before the smaller PS/2 mini-DIN took over in the late 1980s and early 1990s. Today these keyboards are sought by hobbyists maintaining vintage IBM-compatible systems, retro computing enthusiasts, and anyone operating legacy industrial or embedded PC hardware that still uses the AT keyboard interface. A PS/2 adapter (not included) can make this keyboard compatible with PS/2-era systems as well.
