Terminal Oriented Social Science

project (TOSS) The Cambridge Project Project MAC was an

ARPA-funded political science computing project. They worked

on topics like survey analysis and simulation, led by Ithiel

de Sola Pool, J.C.R. Licklider and Douwe B. Yntema. Yntema

had done a system on the MIT Lincoln Labs TX-2 called the

Lincoln Reckoner, and in the summer of 1969 led a Cambridge

Project team in the construction of an experiment called TOSS.

TOSS was like Logo, with matrix operators. A major

feature was multiple levels of undo, back to the level of

the login session. This feature was cheap on the Lincoln

Reckoner, but absurdly expensive on Multics.
