Thanks for the program, but maybe you can help me with it a little more. I got the program running on my IBM AT (Original 6MHz version), but it dies occasionally with a message "floating point error: DOMAIN" I'll try to see if it dies consistently on certain settings, but it for now, it appears to be random. I also tried to run it on my PS/2 model 60, but it dies after the main menu with a message "Please rename to (sic?) program to cosmos.exe". For what it's worth, my PS/2 is 100% IBM, and so is my AT, execpt it has Samsung EGA monitor CD-1453M1. THey both have a math chip. From what little I saw, it seems pretty interesting. What's the difference between Full-Function version and this demo version?
