Key Tronic Model F clone series is a series of IBM Model F clone keyboards produced by Key Tronic for numerous brands.


Key Tronic copied both the XT and AT layouts of the Model F. The keyboard case itself is quite different from the Model F, and distinct in its own right. The keyboard appears to be the basis for (at least one model of) the Compaq Deskpro 286 AT keyboard.[2]

Print advertisements have been dated to 1983[3][1], and an FCC ID has been found from 1982.[4] The keyboards appear to have been tactile from the outset (with linear versions produced).

These keyboards use windowed keycaps for the lock keys, instead of an LED cluster. The keycaps use double-shot moulding.

In at least one instance, the PCB has been found to have hand-drawn traces.
