So now that TAG is also released and Rich has attached a BSD license to all the code, I've made an effort to compile it, and put the result up on SF: http://olympiapbem.sourceforge.net/
If anyone is interested in running another game or just looking at the source together, drop me a line. It's all fairly ancient C code (a lot of K&R, definitely predates C89).
Enno. PS: Thank you, Rich, for relasing the sources. Olympia is one of the first PBEMs I knew, and I remember spending a whole weekend reading the rules and being fascinated by it, but never actually played - I was a student on a budget. I ended up playing Atlantis for years, though, so thanks for your contribution to getting me into the hobby (and eventually, a game development career) :-)
