Notable features of Orion

The Orion Computer was design by Ferranti Ltd. and announced in 1959. It is a binary machine with time-sharing capability and uses an operating system called OMP (Organisation and Monitor Program). Because of the unpromising state of COBOL at that time, a commercial language NEBULA was designed specifically for the Orion. It goes out of commission in 1976.
So that many of its valuable and noteworthy characteristics do not become forgotten with the machine's demise, the following project was drawn up as a joint ICP/PACL effort. Hopefully it may be used, in part or whole, as an aid to forthcoming design.
