Cambridge Algebra System Explained

Cambridge Algebra System
Developer:	David Barton, Stephen R. Bourne, and John Fitch
Operating System:	Titan computer then Cross-platform
Programming Language:	Titan assembler, ALGOL 68C, BCPL
Genre:	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] 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]
