X windows sycrate calculator

[John W]

I did enter the sync rates explicitly due to the fact that is the way
my manual lists them and when trying a range as 31.5-56.6 I could not
get X to work at all. I do have an 800x600 display now using the
calculator. I can see everything without straining my eyes which is a
relief.
I looked at the modelines you made for me and they were in the xconfig
file but I wasn't able to get a working 800x600 resolution. I
appreciate your help and time offered.
