Cracovians Anyone? How do they work?

Cracovians seem to be matrices. I'm looking at some right now, but how they operate is not clear. Braces are used to enclose them. jpg shows the idea.

They belong to the early days of computing when tapes were used for memory. See <http://dictionary.sensagent.com/cracovian/en-en/>
