Perseus was a vacuum tube (valve) computer built by Ferranti Ltd of Great Britain.
[1] Perseus, which was one of Ferranti's computer systems that included Orion and Sirius,[2] was the company's first production machine marketed towards commercial users.
The envisaged applications would involve vast amounts of file data, for which 1/2" magnetic tape was provided.
Many years later an eagle-eyed employee spotted some of the decommissioned Perseus enclosures at the back of the building, ready to be scrapped.
The staff member purchased the about-to-be-scrapped enclosures for next to nothing and eventually built himself a sports car from the "Made by Rolls Royce" aluminium sheet metal!
