This keyboard was standard equipment with Compaq Presario and Deskpro desktop computers during the late 1990s and early 2000s. The Enhanced III keyboard is compatible with any system featuring a PS/2 keyboard port — including older Compaq, Dell, HP, and generic PCs from that era.

These keyboards are still actively used by retro-computing hobbyists and in businesses maintaining legacy Compaq systems. The durability of the mechanical design means many units remain fully functional decades after manufacture.
