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.
