While the H11 was popular with hard-core hobbyists, Heath engineers realized that DEC's low-end PDP-11 microprocessors would not be able to get Heath up the road to more powerful systems at an affordable price. Heath/Zenith then designed a dual Intel 8085/8088-based system dubbed the H100 (or Z-100, in assembled form, sold by ZDS). The machine ...

Despite these defects, the Flash-matic remained in high demand. In September 1955, Zenith apologized for its inability to meet the consumer demand. [4] [5] The Flash-matic was soon replaced by better control systems. The "Zenith Space Command" remote control went into production in 1956 with aims to improve upon the Flash-matic's design. [6]
