L to R, Doug Calli and Stan Holmes. The "hot-swap" telescope controls were multiplexed to 3 locations within the set, allowing operators to manipulate the telescope from any location.
Status conditions, i.e. rotation count, axis limits, emergency stop, hydraulic pump controls and others, were displayed on each controller. Microprocessor circuit boards, designed by Doug
Calli for the show, provided these necessary functions.
