Who came up with those changes?—it may have been at DEC for the PDP-11.
peek and poke were microcomputer additions
The string editing things were additions from Tymshare for Super BASIC on the SDS 940. I was told Super BASIC's extensions on the Harvard TSS 940 system was the influence for those functions in Micro-Soft BASIC.
RSTS BASIC on the PDP-11 had many of the same extensions which carried forward into DEC's other implementations of the language.
I found a collection of BASIC users manuals for many different systems in the CHM archives a while back, so bitsavers.org has a collection of many of them filed by manufacturer. I had been researching where the language changes originated from for a paper, which I never finished.
