Another track inspired by a visit to the National Museum of Computing at Bletchley Park.

The Commodore PET (Personal Electronic Transactor) was one of the first personal computers, released in 1977 by Commodore International. It was an all-in-one machine with a built-in monochrome monitor, a keyboard, and a cassette drive for data storage. It ran on the MOS 6502 processor and was one of the first widely available computers designed for businesses, schools, and hobbyists.
