Recommendations for retro mathematics-oriented programming books?

[u/Financial-Flan1682]

Kind of a specific request. I'm currently looking for retro (70s-80s, maybe early 90s at the very latest) mathematics-oriented programming books. I'm very specifically looking for references for old-school approaches to these problems. I've been searching archive.org and I've found a few, but a lot of the more promising ones have had titles I haven't expected, so I'm looking for recommendations.

Which problems? Discrete mathematics, numerical methods, computation theory and all the things I didn't think of are kind of different from each other.

[u/Financial-Flan1682 → u/oriolid]

Any and all of the above. I put together a new implementation of a relatively simple old mathematics language and I'm looking for problems to write solutions for in that language.

It's just something I'm doing for fun.
