The LGP-30 (MINAC) was developed by Stan Frankel, a physicist. This design was asked to be developed from a company named Librascope. The LGP-30 was a desk computer mainly used for science and engineering. It was sold for $50,000 and was meant for one user, resulting in it technically being the first personal computer.
Famously in a Computer Museum in Boston, judges declared that Kenbak-1 was the first personal computer. Kenback-1 was designed in 1971, and it was built using small-scale integrated circuits
