Well, my experience matches Johnny's. I used many derivatives of
MicroSoft BASIC - PET, Apple INTBASIC, Applesoft, Exidy Sorcerer, and
others - and they all start at 0. AFAIR HP BASIC did so as well. The
original 1960s Dartmouth BASIC (for which I have a copy of the manual)
also started at 0 (cf. page 38); indeed if you didn't explicitly DIM an
array, you got eleven elements indexed 0...10.
