Oh boy - I've literally just come out of Turbo Pascal 3.0A on a Z80 retro rebuild - I've hacked together some code to run a 7-segment clock/timer board I made for my Commodore 64 in about 1984.
Turbo C++ 3 is still popular in parts of the world. There is a steady trail of people on the various C++ forums asking why modern code they copy and paste fails to compile on Turbo C++, and why code that works on Turbo C++ fails so miserably when fed to a compiler less than twenty years old.
