alt Hacker NewsPascal was poised to be the de facto language for microcomputers back in the 80s and early 90s. It really could have gone either way.
I'm not sure what tipped the balance to C/C++. Maybe the Microsoft compilers? Maybe the merge of the minicomputer world into microcomputers? Either way, Pascal held on (via Delphi) into the early 2000s.
2007-2012 I was still writing code in Borland C++ Builder 5 which shared a lot of code libraries with Delphi.
Our microcontroller code was written in Turbo C++
