I remember that using x86 assembly was consensual in the Turbo Pascal 
(later Borland Delphi) community as well. Delphi could not deal with the 
floating point unit properly, and Borland did not care, so typically all 
numerics in Delphi programs were done in assembly. And the Delphi 
community did not seem to care. Even more strange, Borland did have a 
C/C++ compiler as well (Turbo C, later C++ Builder), which created 
object files binary compatible with Delphi (and incompatible with 
Microsoft C). But even still, the Delphi community preferred assembly to 
C for speeding up floating point operations. Sometimes it can be hard to 
understand human behaviour.

I was born 30 year ago, but at that time we could not afford a 
television set. And where I lived, FM radio broadcasts were still in 
mono only. Using satellite antennas for television was a felony. And it 
was prohibited for any store to be open after 4 PM. Needless to say, I 
had very little knowledge of computers at that time.
