Representatives from Digital Equipment Corporation demonstrated the Rainbow 100 and Rainbow 100+ microcomputers in the College Center. The Rainbow was chosen as the first personal computer for Vassar faculty and staff after a delegation from the college, returning from Cupertino, CA, the home base of Apple Computer, reported seeing prototypes of a microcomputer, to be called the Macintosh, but said the company’s strict confidentiality constraints they had agreed to forbade their sharing any further information.

Relatively little software was ultimately written for the DEC Rainbow.
