RM was founded in 1973 in Oxford, England by Mike Fischer and Mike O'Regan, respectively graduates of Oxford and Cambridge Universities. Initially it traded under the name Sintel which was a mail-order supplier of electronic components, mainly dealing with the hobbyist market. Fischer and O'Regan's ambition was to grow their business into a manufacturer of scientific equipment, with the educational and scientific market chosen because they judged that their business would not be able to grow fast enough to be successful in the general computer market that they expected to be dominated by existing big players.
With the arrival of microcomputer chips in the mid-1970s, the company expanded into the design and manufacturing of microcomputers. The company shipped its first computer in 1977 to a customer in a Local Education Authority and has been involved with educational computing ever since.
