Other marathon series done with calculators (and not only)?

[rprosperi]

I'm not sure if you are referring to the documentation or a marathon series of programs...

If the latter, a must review selection, possibly the most impressive of all, are the programs written and shared by Prof. Dr. Wolfgang Rautenberg. Though ha sadly has passed away, his magnificent collection has been preserved and is available here:

Note that many of his programs are in the utility / system s/w category, rather than pure mathematical applications, but these are a least as interesting, and for me personally, even moire so.
