Some would be difficult.  IE Chess 4.x was written in CDC assembly language
(Compass).  Belle was built around special-purpose hardware which would mean
it would be impossible to use without it.  Hitech was the same.

Pioneer never existed (this was Botvinnik's program and it never played a single
game).

Nuchess was written in fortran.  Slate almost certainly has a copy of this
laying around.  Whether he will give it away is another question but I would
suspect he would.  Kaissa was written in a high-level language, but I don't
recall if it was FORTRAN or something like ALGOL.

Deep Thought had special hardware.  The software on the winboard site is simply
a program used to tune its evaluation parameters.  Didn't work for DB1 or DB2
as the evaluations were much more complex.
