Irrelevant. The BGI drivers won't work in either one.

NASM would be another show stopper in that case, as it too has a different syntax than the inline assembler of Turbo Pascal. And yes, there is no native FreePascal compiler on DOS, you have to use either a Windows or a Linux based cross-compiler.
The best chances for him would be to get the Turbo Pascal 5.5 compiler from the oldies section at Embarcadero or try and get a copy of Borland Pascal on EBay, if those are still around...
