Fairlight USB2CMI - USB mouse, keyboard and MIDI adapter for Series II/IIx/III - No display

The Fairlight CMI USB Lightpen Interface replaces (or complements) the original lightpen with a standard USB mouse, making navigation faster, easier, and far more accessible. Designed specifically for Fairlight Series I/II/IIx, this compact interface bridges vintage hardware with modern usability.

Originally designed in 2010 by Joe Britt, in 2026 Joe and Deftaudio have redesigned it for better look and feel, added an extra cursor mode, aluminum enclosure and powder coated side panels with silkscreen.
