I just saw these in the update section, and it doesn't say who posted them (that I can see).
Whoever you are, Thank you very much!
I played hours and hours with the 1973 edition, and this is a welcome update. Stuff happens in 40 years, you know.
The author of those files, and several Bowl Bound files, as well, is Phil Loscoe. He has been very active uploading files the past weekend. Great Stuff!
