General Precision LGP-21
c. 1966

This general purpose computer was the descendant of the LGP-30 which contained both vacuum tubes for the CPU and solid state diodes for the logic board. The LGP-21 was all solid state, made of transistors, which meant it was smaller and less expensive than its predecessor. The Museum has in its collections one of the last LGP-30 models produced by Librascope and currently displays both on the main floor exhibit hall.

Donor: Michael Parks of Moreno Valley, California
