PLATO Empire source?

(Actually, I most often played R.) I built an attempt to recreate it based on decade-old memories sometime in the late '80s, which I recently dusted off (for those with git and curiosity, git://git.rodents-montreal.org/Mouse/games/0empire should be clonable). Looking at the screenshots, though, it's interesting how much I'd obviously forgotten, and the text there makes it clear there's also a lot more I never knew. The main reason I'm interested in the source to Empire is to make my recreation of it behave more like the original. I'm not trying for a total clone - if that's what I were after I'd be looking for a PLATO simulator to run the original on - but something that feels not too unlike it while still being recognizably a little more modern (for example, using finer resolution on the display). This is obviously a balancing act.... /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
