Downgrading old pc to 98, worth it?

Awhile back I got a Toshiba Satellite with Windows 7, it wasn't great from the get-go, so it's been in storage for awhile. I'm planning to recycle it at the tech shop, however I want to play around with it a bit before I take it in. I was thinking about downgrading to 98 on it, but is it worth it, or is it too incompatible with the system? I mainly want to do this just to see if I can, I also miss windows 98 on a physical machine (I have both versions of it in virtual on my main pc.)
