Wyse ASCII keyboard is a Wyse terminal keyboard designed for the Wyse 60 terminal. The Wyse ASCII keyboard is very similar to the Wyse 50 keyboard, but without the stepped keycaps and with a 4P4C modular connector instead of 10-pin DIN. The Wyse ASCII also has the same layout as the Wyse ANSI; the difference between these two is not known, only that the Wyse 60 terminal has both ASCII and ANSI personalities.

Keycaps for the Cherry MX Variant were made by Signature Plastics. Space bar is 9.75 units wide, with one centre mount and 2 stabiliser mounts 3.5 units from the centre.
