Very nice indeed, Luis! Congrats! Those little thingies are pretty scarce. Do you happen to have the original power adapter? Mine didn't come with one and I have absolutely no idea what kind of voltage it's supposed to output, or if its power plug is center positive or negative...
IIRC, the Pro came with a PSU while the original one didn't. I guess 5V from the ADB port was enough for the first iteration...
I asked someone at France Telecom and apparently you can't use it anymore on their network (even with an old pots line). But, approximately three years ago, I started a thread on Apple Communities (way back when I had no idea the 68kmla existed), and apparently
there's a work around. Long story cut short, it requires a specific Airport base station. And FYI, at some point in that thread I was rambling about the seller stabbing me in the back and deciding to sell the thing to someone else... but the other buyer backed out and I got the Djinn in the end. Yay for me!
It's sitting partly disassembled in a cubberd somewhere. I really need to get back to it. Now that my good old pal has one as well, I've got no excuse not to at least try to get it working.
