-'''Technology Square''' was the nickname for [[MIT]] building NE43; its formal address was '545 Technology Square', but everyone just called it by the shortened form, '''Tech Sq'''.
+'''Technology Square''' was the nickname for [[Massachusetts Institute of Technology|MIT]] building NE43; its formal address was '545 Technology Square', but everyone just called it by the shortened form, '''Tech Sq'''.
 The Technology Square complex contained other buildings; in about 1968 the Beta building, a virtual clone of the 545 Tech Square building, was built on the other side of the main courtyard, at 575 Tech Square. A [[Honeywell]] branch, [[CISL]] (probably 'Cambridge Information Systems Laboratory'), where much [[Multics]] work was done, was on the third floor of Beta. [[Computer Corporation of America]] was housed on the fifth floor of Beta.
