Tektronix 466 question

I am a novice(at best) and i just upgraded scopes to a used tektronix 466. I haven't even gotten it yet but was doing a bit of reading up on it, and noticed on several sites the description states it is designed for "non-repetitive or slow moving signals". It is a 100mhz scope, but i have not found anything on its sample rates. I read the manual and it leaves me wondering where this statement comes from. Am i missing something important? Any help would be great, and thanks.

It's a storage scope

I think i figured it out, I had it in my head that is was a limitation. But it is more of a feature... Right?

Thanks for the fast reply
