I'm reading a history of Borland and the author claims that the Turbo Pascal compiler was mostly written in assembly and was also used in Delphi 1.0. No one in Borland could make significant changes in the code so eventually they rewrote it for Delphi 2.0. Not sure if all was true but very fascinating. I think there is a certain character in programmers who went through the fire and storm by writing softwares in assembly language for non trivial CPUs (like Pentium and up) that is unique.
