(Yes, I got 2.)
I have three. Together they have 22.5 digits.
Currently they are stored at some friends of mine. Will get them later this year hopefully.
Sweet.
Your tasks will then be to get three connectors, connect them in parallel to a suitably stable source, and display all three readings simultaneously. For bonus points, measure the noise.
Yes. The thing is: I've bought from this seller (ebay Kleinanzeigen) just one of them, got a lower price than he was asking for. (wanted 350 Euros, got it finally for 280 including the cable with the Fischer connector). Then, three weeks later or so he came back to me and asked, if I want to buy another two of them. He found them in his basement, condition unkown. Offered me them for 100 Euro per device. And guess what? I said yes.
So, I'll check them first if they are working. If not, I hopefully have then one or two parts mule. But by the look I think chances are good that they'll work. If they are working, I'm considering to offer them here. If somebody would be interested.
