oldest bits in Squeak?

I recall there being a surprising number of extremely familiar methods in
the examples & illustrations in the books released in the early 1980's for
Smalltalk-80. Until quite recently you could find matches in Squeak and
VisualWorks. Haven't done any comparisons lately, though. The early Squeak
releases seemed to be basically color versions of Smalltalk-80.
Get much earlier, and you will be seeing Smalltalk-76 code. Alan & Dan will
have to fill us in on the progress prior to 1980.
OTOH, there was a Smalltalk-76 "emulator" provided at one point to run
within Squeak. So... have a look in there if it is still around. The
syntax will be a bit different... but perhaps the underlying image remains.
Wasn't there a Smalltalk-78 that was basically very very similar to
Smalltalk-80?
