I do remember something that one of the artists had said in the forums and correct me if I'm wrong but.....when some of the artists would do 3d Renders (like you see on the covers, or even in the manuals, etc.... Sometimes the artist would start the hi resolution 3d render the night before and hopefully when they came in the next morning/day the render just might be done? And I remember that was on a 486 machine. Back in the day I don't believe the O/S programming was all that fast. Amazing.
Has nothing to do with storing text files, though. I can understand that they needed a fast 486 for the compiling, but even several megs of text files were storable on any 386.
This story should be included on the Mobygames Strike Commander trivia:
