That sounds kind of cool, but although the binaries of Turbo Pascal are now downloadable from Borland's successor at no charge, the source code was never released. That makes the proposition less interesting than it would otherwise be. BDS C source code was released into the public domain a few years ago, so that might be an alternative. Or you could use MSDOS/FreeDOS that would give you a lot more flexibility while staying a similar text-based spirit.
It’s my path to $2B.
Don’t tell anyone my idea.
