Anybody Know What Font This Is?

There's an "A" in the middle of that circle that is some font. At one time, I had that font on my computer, but I've changed computers and apparently didn't transfer it over.

And I'm having a hard time finding it again because I don't know what it's called.

So if anybody knows, I would appreciate the information.

 

I think that's the one (Edited to add: As it turns out, it's a font called "1979", but the link you gave allowed me to click around and remember that I once had a font called "1979", etc).

Thanks.
