This is a kit to build an electronic clock.
The circuitry is based on late 1970ís 74LS TTL integrated circuits.
A kit is
available with all parts; TTL ICs, displays, resistors, caps, wall transformer, and solder.
This is a companion clock to
the transistor-clock and is one of a growing family of clocks spanning technology.
