The Halcyon was a home video game console released in January of 1985 by RDI Video Systems.
The initial retail price for the system was $2500, and it featured a
laserdisc player and attached computer, each the size of an early-model
VCR. Only two games were released for the system before RDI went bankrupt: Thayer's Quest and Raiders vs. Chargers, although trailers for several others were created. RDI Video Systems claimed that the system would be entirely voice-activated, and would have an artificial intelligence on par with HAL from 2001: A Space Odyssey.
