By this point in college 30 years ago I had switched to mostly emacs, and was struggling with it - our program was unix based (solaris) with gcc. But a few years before that I was using turbo pascal, which was indeed a very fast ide, partially by virtue of how low latency hardware was back then.

I like these programs, mostly for that sweet low latency which is just gone today, but I wouldn't romanticize them as dev experiences. To experience it you can download free pascal today and use theirs which is just like turbo pascal (may even based on turbo pascal?). Its pretty clunky compared to what you get today, although, the debugger works which is more than what you can say for the majority of languages today.
