Came here to share this mandatory link on this subject, Dadgm's Things That Turbo Pascal is Smaller Than: https://prog21.dadgum.com/116.html

I used Turbo Pascal 2 as late as 1991, if not later, because that was the version we had. It was really fast on a 386 40 MHz or whatever exact type of PC we had then. A bit limiting perhaps that it only came with a library for CGA graphics, but on the other hand it made everything simpler and it was good for learning.

A few years ago I wanted to run my old Turbo Pascal games and decided to port to Free Pascal. Sadly Free Pascal turned out to only ship with the graphics library introduced in Turbo Pascal 4, but on the other hand I got a few hours of fun figuring out how to implement the Turbo Pascal 1-3 graphics API using inclined assembler to draw CGA graphics, and then my games worked (not very fun games to be honest; more fun to implement that API).
