Many that won't run are written in Turbo Pascal.  It is a timing issue on
program start where it initializes a variable.  The program won't wait for
that to happen, and you see a "Divide by zero" error.  There is a patch, but
it only works on machines that are under maybe 600MHz or so.

If anyone has such a program and wants to try that patch, contact me off
list.  IIRC, the patch name is TPPATCH.EXE or very similar.

I have a 1989 DOS game of Risk that runs fine, mouse and all on a W2K 3.2GHz
Intel machine.  It's a program that was sold by Radio Shack back then.
