The RCA Lyceum TV was a commercial monitor/receiver with a large input/output panel on the back, and a 20-foot (6.1 m) long grounded plug.
During the mid-80s, RCA released the Colortrak 2000, a television identical to the Dimensia table-top model.
The Lyceum TV, Dimensia, and Colortrak 2000 models all basically had the same chassis (a wood grain veneer, or black laminate for some Dimensias, and fabric covered speakers on the sides of the cabinet).
[citation needed] Many Colortrak 2000, Lyceum, and Dimensia TVs came packaged with a very large remote control, the Digital Command Center.
The Dimensia version of the remote was called the "Dimensia-Intelligent Audio Video" and had identical buttons to the Digital Command Center.
