CRT and Turbo Pascal Windows

I have a new computer (300mhz) and the CRT unit bombs.  I know its because
of the delay.  I'm currently using a patch someone made.  But I would like a
clean fix, that requires the RTL code that I either don't have or lost along
the line.  Is there anywhere I could get the fixed unit?  If not, anyone
know of a good site to learn Pascal for Windows?   Its alot the same but all
the windows stuff confuses me.
