The Electrologica X1 was a digital computer designed and manufactured in the Netherlands from 1958 to 1965. About thirty were produced and sold in the Netherlands and abroad.
The X1 was designed by the Mathematical Centre in Amsterdam, an academic organization that had been involved in computer design since 1947, and manufactured by Electrologica NV, a company formed expressly for the purpose of producing the machine.
The X1 was a solid-state binary computer ("completely transistorized") with magnetic core memory. Word-length was 27 bits and peripherals included punched and magnetic tape. It was one of the first European computers to have an interrupt facility.
The X1 was the subject of Edsger Dijkstra's Ph.D. dissertation, and the target of the first complete working ALGOL 60 compiler, completed by Dijkstra and Jaap Zonneveld. In 1965, the X1 was superseded by the X8. Electrologica was taken over by Philips a few years later.
