/diy/ - Do It Yourself

I've found some old Soviet 7-segment displays and want to hook them up; problem is, they're all common-anode, and I'm too stupid to figure out how to control them. The best guide I've found so far is pretty poorly written (or at least in a way I can't read it), can someone please help me out here? I'd love to put these to use. Pic related is very similar to what I have but not mine.
