I think the answer is that because by that time an OS was written in
Assembly and for everything else you used Algol pretty much (and Cobol). But
I remember that early 80's I was already programming in Turbo Pascal 3 on
the Z80 Softcard (the Z80 based CP/M expansion card by Microsoft on an Apple
II). For a very long time Turbo Pascal on CP/M and later on on MS-DOS was
very very popular. Also other Pascal implementations on Apple Mac was the
main development stream, C was just an alternate language. It was not just a
random thoughts from Borland that they pushed Delphi by that time instead of
one of their many languages they had. Yes, they had the Turbo C/C++ compiler
as well but that was only the second in the popularity list (and MS C was
even less popular).
