Actually I own both, the A and B. Not pristine, but working. However, I wouldn't swap them for a vintage car. At some point I have to think about what to do with them but hopefully this moment is still far away.

You can see one in action in this video, e.g. at around 17:20. A quite a big device to show the contents of the X,Y and Z registers.

I know only of one such display that has survived in the Computer Museum of the University of Amsterdam. It looks like the museum can only be visited on written request. I'd really like to see one in action.
