Actually, the "Triad" interface is the MIDI interface, called that because
it was originally supposed to support peer-to-peer networking via token
passing, but that was never developed.

The only adapters I've seen for the 25-pin Chroma interface are a couple
Chroma-to-MIDI converters for the original Chroma, which didn't have MIDI.

If you want to build your own Chroma-to-USB interface, the Polaris
schematics and service manual are in the files area of this group.
