This is the one you’ve been waiting for—an early production IBM Model F XT Keyboard with Capacitive Buckling Springs. Its clicky, all original 83 keys all sound beautiful and none of them are sticky. The internal sticker across the very clean metal plate shows its production information along with hand-written initials of its assembly team from 1985. This F XT’s early shop date is 5043 makes it one of the oldest units identified in public databases. This is a rare gem.
