Sorry, no new info, other than that we're on our own except for those schematics. Maybe this summer, I can take a look at them and puzzle out what to connect to where, but I have exams in two weeks, no time now
If somebody does manage to get one going, please post it so we can enjoy your work!
There was another site that had them, I think it was surplus traders.net, here's the link, it's about halfway down the page in a yellow box, titled 'LCD readout for cellular phone and more'
