The C. Itoh CIT-220 terminal was compatible with the DEC VT220. It was introduced sometime before August, 1985.

The CIT-220+ variant was introduced in August, 1985 at a price of $995. It included an enhanced keyboard compared to the CIT-220.[1]

DEC had alleged patent infringment by C. Itoh on the terminal, but lost a lawsuit in the matter.[2] The lawsuit was settled with an agreement by C. Itoh to stop selling the CIT-220+ and change the format of its setup screens.[3]
