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?
