TicTac (Fab Dynamic)

About This is a simple tic tac toe game that wont blow your mind. How it was made I made it in 16 bit real mode ms-dos and it should work even on ancient machines. I made it in Borland TurboC which I installed using these instructions but it only uses bios interrupts so it was tricky getting all of them working to the required level and also I couldnt even figure out how to get two pieces of register data back from those commands. The binary is just 8,226 bytes. How to run it? It will run on mac...
