Description
Dell AT101W 9772C PS/2 Keyboard 101-Key GYUM90SK Mechanical IBM Compatible
The Dell AT101W is a full-size 101-key PS/2 keyboard built to IBM-compatible PC standards. This example carries Dell part number 9772C and features the GYUM90SK switch assembly — a Monterey-manufactured mechanical switch mechanism that produces a tactile, clicky keystroke characteristic of high-quality keyboards from the mid-to-late 1990s. The keyboard connects via a 6-pin Mini-DIN PS/2 plug and follows the classic AT101 layout with a dedicated function row, main alphanumeric block, navigation cluster, and numeric keypad.

Applications
The Dell AT101W belongs to a generation of full-travel mechanical keyboards built for IBM-compatible desktop PCs throughout the 1990s. PS/2 keyboards of this type were the standard input device for PCs from roughly the late 1980s through the early 2000s, when USB gradually replaced the PS/2 port as the dominant interface. The AT101 layout, standardized by IBM with the Model M and adopted across the industry, remains familiar to touch typists and is still preferred by many users who favor the consistent key spacing and dedicated navigation cluster over more compact modern designs. Today, these keyboards find use with legacy PS/2-equipped workstations and industrial PCs that still run with PS/2 ports, as well as with collectors and enthusiasts who seek out 1990s-era mechanical keyboards for their tactile feel and build quality. A PS/2-to-USB adapter (sold separately) allows use with modern systems that lack a native PS/2 port.
This Dell AT101W 9772C PS/2 Keyboard was pulled from a working environment where it was previously in use. The keyboard has been visually inspected and is in good used condition. Keys appear to be all present with no missing or broken keycaps. The beige plastic shows light yellowing and surface wear consistent with normal age and use on a vintage keyboard of this era — no cracks, heavy staining, or damage noted. The PS/2 cable is intact.
