Burroughs Large Systems (B6700, B7700, et al, and A-series) 
have been doing dynamic linking for many years.  
Originally it was only done for system
library subroutines; 
there was a single 'intrinsic' library that was linked to
at the first reference for each subroutine at run time.  
Today, Burroughs has
gone wholeheartedly towards run-time binding 
to library subroutines.  In fact,
they wanted to eliminate the static binder 
completely, but the user community
made them keep it.  (It had always been buggy, 
and Burroughs didn't want to
fix it.)
