Since I see it's finally been mentioned here, I'll address it (and no, I couldn't make it there - the board in question is owned by dfj, and I did supply him with it):
The "Kishsaver" as a small group of GH IRC members named it 1-2 years ago is going to be properly revealed when I finish writing a web page for it, complete with photos and other information about the system it's actually for. Complete with that information will be pointers to help locate them, but they are very hard to find, and the vast majority of sources who claim to have them, do not.
Some people here know its full identify and information, and to them I provide continued thanks for not spilling the beans - I likely won't have any motivation to publish the web page anymore if that happens (what's the point?).
ETA on the aforementioned web page is "soon"; it's my only real project currently aside from my car.
