I use Emacs both on Linux and Windows. Long ago I even tried the DJGPP port on DOS (anybody out there who remembers it? :-)).

Emacs packages I use frequently

Welcome on the Wiki ! :)

I remember the DJGPP port. :)AlexSchroeder

Wasn’t that horrible DOS window ? I remember using it as my first Emacs, and later I discovered NTEmacs. – LucasBonnet

Sure! But at the time I didn’t have Windows! :)AlexSchroeder

Actually this made me try Linux: Everytime I tried to start Auctex under DOS the machine crashed. So I decided to try a real operating system :)) – MartinStemplinger
