Harvard had an SDS 940, which shipped with a version of Berkeley's timesharing
system. Tymshare's version of that system was significantly improved, and included
"Super BASIC". SDS's OS was replaced with Tymshare's at Harvard because the original
was so bad, and so they were exposed to that version of BASIC. PA told me that was
the influence for M-S's BASIC extensions.
