Operating system	Titan computer then Cross-platform
Type	Computer 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]} In 1973, when Titan was replaced with an IBM370/85, it was rewritten in ALGOL 68C and then BCPL^[4] where it could run on IBM mainframes and assorted microcomputers.^[5]
