RM Education was founded in 1973 as "Research Machines" in Oxford by Mike Fischer and Mike O'Regan. Initially it traded under the name Sintel as a mail-order supplier of electronic components, mainly dealing with the hobbyist market.
With the arrival of microcomputer chips in the mid-1970s, the company expanded into the design and manufacturing of microcomputers.
