Cambridge Algebra System

Cambridge Algebra System (CAMAL) is a computer algebra system written in Cambridge University by David Barton, Steve Bourne, and John Fitch. It was initially used for computations in celestial mechanics^[1][2] and general relativity. The foundation code was written in Titan computer assembler.^{[3][better source needed][4]} In 1973, when Titan was replaced with an IBM System/370 Model 165, it was rewritten in ALGOL 68C and then BCPL^[5] where it could run on IBM mainframes and assorted microcomputers.^[4]
