Some of them may fit (E.g. Thinker is a good candidate).

Of course, the modern programs have modern CPUs in mind.

For instance a bitboard program will do great on native 64 bit integers.

On a machine with no such thing as multiply and with 8 bits as the largest
native type, the emulation is going to stink.

So, I guess the upshot is that in theory it is possible to port them.  In
practice, even if it works, it's not going to be pretty.

Another possibility is an emulator:

Which is the opposite approach.   Take an old program and run it on a new
machine without having to recompile it.
