Seen on eBay, a prototype of the 1990s Apple TV. For $450, you’ll get a device containing a kind of Mac (with a 68040 CPU) and american video outputs, with the Peritel outputs disabled. Please note, the device isn’t really functional: the network doesn’t use Ethernet, and in 2014, MPEG1 is rarely used.
I had previously talked about the enclosure over here, and it’s still a bit pricey for something that can be fairly easily found for a prototype…
