No, but I don't buy the "pascal compiler" BS. The first common 
architecture on which a Pascal compiler was implemented was the PDP-11, 
a strongly orthogonal, memory-mapped I/O, "Motorola-type" architecture. 
The later, common, P-system was based on a virtual stack based 
architecture. Intel's segmented architecture isn't close to either, and 
provides no unique benefit for a Pascal complier.

It's strange that neither the contemporaneous literature (notably the 
Osborne microprocessor book series), nor current community consensus 
(Wikipedia) makes any mention of Pascal as the cause of Intel's 
segemented architecture.
