Heathkit clocks have been among the most popular kits of all time. The Heathkit GC-1005 was the first digital clock kit and also the first in a series of line-powered Panaplex display clocks first introduced in 1972. The clock uses three Sperry (Beckman) SP-352 two-digit Panaplex gas discharge displays and was designed around the Mostek 5017, the first integrated circuit ever made that contained a complete “clock-on-a-chip”.
This Heathkit Digital Clock was meticulously assembled in 1973. It is in perfect physical and operational condition; it keeps perfect time with all functions in working order.
Also included is the Assembly Manual, Kit Builders Guide and Schematics.
