Where can I find or donate software of historical interest?

Question

Computer science and programming is a field with a relatively short history but it is developing very rapidly. Is there a repository for existing historical software or somewhere that I could submit software of historical interest?

I've asked this, and answered using the standard SO paradigm, because I thought it would be of general interest to the community.

Answer 1

I am aware of only one repository for historical software, the Software Preservation Group. It contains items of interest for C++, LISP, and Fortran among other topics.
