- Various model sof Intel chips are far less compatible with each other
- than with the AMD chip. Don't be worried.
-
- mcm> I want to write software which will run on any IBM or clone.
-
- This is an amazing goal. I doubt very much you can achieve it. Just
- consider the enormous variety of video cards. Just consider the variety
- of DOS versions. Just consider the variety of buses.

-
- The answer in short is *NO*. There is no way to ensure complete
- portability in the PC world, but for the most trivial of program.
-
- On the other hand the people who have written the Tubo C compiler and
- libraries have already tried to make them as portable as possible.
-
- So unless you inadvertently code in your program bugs or features that
- depend on the specific configuration of you development machine (of
- which the CPU brand is the least of your worries), you do careful
- defensive programming, and so on, then using Turbo C for your program
- will give you as much portability as possible.
