Hyperglide vs. Uniglide?

Hello everybody.
I got a old road bike set up with Shimano 600 all through. My questions is now this, is Shimano 600 uniglide? And what a heck is uniglide, (what is hyperglide also), and what is the difference between hyperglide and uniglide that makes the cassettes non-compatible as someone said?

Check out http://www.sheldonbrown.com/k7.html for the lowdown. Check the side of the smallest gear against the pix in that article, you'll be a Shimano archeology expert in 5 minutes.

600 was uniglide early on with 6 and 7 and hyperglide later with 7 and 8 speed.Spline pattern is different, and uniglide uses a screw on first cog rather than a lockring like hyperglide.

Uniglide was also the name given to Shimano chains for their 5-speed freewheels (25 years ago, or so). The outer plates were bent to achieve a wider opening every other link. Facilitated shilfing. (The teeth on the largest sprockets were slightly offset and twisted for the same goal.)
