The Model F first appeared with the IBM System/23 Datamaster all-in-one computer. It is best known as part of the IBM Personal Computer in 1981 with some keycap label differences, and its subsequent release with the IBM Personal Computer/AT, where it was reconfigured with the AT protocol and some layout revisions.

Each character is rendered in a box of 9 × 14 pixels , of which 7 × 11 depicts the character itself and the other pixels provide space between character columns and lines.
