Hmmmm. Looks like the new iPod can spit out its serial number on command (nothing new, except to this menu). And wow, amazing how hot that hard disk can get; the mini runs so much cooler at peak. Then there’s that status test. On the mini, it says “WINTKLCD,” and on the 4G, it says “OPTRXLCD.” Component sources for the screens, or something else? The other stuff on the screens means headphones (yes/no), with or without FireWire Power charging, and with or without USB Power charging. Interesting, it seems to think that an optical TOSLINK cable counts as headphones, but there might just be a physical sensor in there.
(Update: Wintk = Wintek, Optrx = Optrex. They’re component sources.)
