Good old Turbo Pascal - I started my venturing into programming with TP6. Borland had the greatest IDEs back then, the integrated help was outstanding, and TP6's ability to "compile & link to RAM" was _perfect_ when working on a dead-slow 286 with an even slower harddrive
(and yeah, I had a damn lot of green-on-blue as well, you sorta needed that to get acceptable speeds back then).
I'm still stuck with a black-on-white scheme (with additional syntax highlighting - I wouldn't live without that today!), it works well enough and I don't get eyestrain. Been meaning to try out something else, but it just takes too long to fiddle with (Notepad++ doesn't come with schemes to choose from). Green-on-black has always seemed very harsh to me.
In VIM I use the 'desert' scheme, which is pretty nice... but VIM is never going to be my main editor, I'm afraid. It's slightly (and I do mean slightly
, but enough to notice) heavier than Notepad++, and I don't really do stuff faster in it. Great when I'm stuck on linux, though.
