What version of Red Hat?

I’m going to start messing around with linux on an old computer. It’s a Pentium 166, 56 RAM, 40 gig HDD, 3.2 gig HDD, and with windows 98 already. I’m pretty sure that Red Hat 8 won’t run on my system, but I could be wrong. So would you guys recommend Red Hat 6 or 7?

as low as possible , even redhat 6 is pretty much overkill for such a machine
