Plus this one here in the collection/museum at Erlangen University computing
center (where I held a student job):

I think they had taken out most of the cards and stored them in cardboard
boxes for the transport and just put away the panels at some time to set up as
a blinking exhibit too (as the whole logic needed to do that is contained
within them) but all the stuff should still be there. Been nearly ten years
however by now so who knows?!

So long,
