Yes, since VI 2.0 (1983) there is Multiple Inheritance in Smalltalk-80.
A documentation is distributed in every Smalltalk-80 documentation
provided by Xerox Parc, ParcPlace Systems or Georg Heeg for Smalltalk-80
for VI 2.0, VI 2.1 and VI 2.2 DE. 

This contains reprint of 

Alan H. Borning, Daniel H.H. Ingalls: Multiple Inheritance in Smalltalk-80,
AAAI National Conference on Artrificial Intelligence 1982 in Pittsburgh.

The present doumentation (VI 2.2 DE) adds some additional hints for the
usage of multiple inheritance: "... The status of the implementation
provided is similar to an example in that it is nowhere actually used in 
the system itself, and has not been rigorously tested. ..."
