Someone has listed a late 70's/early80's Zentih Space command on ebay. This may interest some who collect from that era.

The price is a high for that age of TV.

This is an early Zenith "big screen". The top half of the TV is designed to lower into the bottom half when not in use. Someone gave me one several years ago with a busted red CRT. Otherwise, the set worked. The thing was heavy as lead and I wound up tossing it. This is yet another seller that thinks they are sitting on a goldmine.
