Hi all. I remember many years ago using a small textmode program called ERATO.EXE or ERATO.COM to benchmark CPU speeds. It calculates the Sieve of Eratosthenes up to a certain number. Does anyone else remember this or have it?

Cool! 😎 Never heard of this before - thanks for sharing. (Except that mathematican himself, of course.)

Perhaps not what you were looking for, but here's another program of that kind. 😀

PS: Seems the benchmark was common for testing Pascal languages.

Edit: Found a PDF that explains the working of the sieve.

Edit: It is perhaps not 100% on-topic, but I know of a few fractal programs for PC/DOS, that are fun, too.
They are not crunching prime numbers, but are also math-related, and run on XTs (w/ FPU), even.

Thanks, I like that page with 147 different language implementations.

The program I remember was free, given away with a magazine, but I no longer remember which, late 80s or early 90s.
