Seen on eBay, an Apple Interactive Television Box. This device, a precursor to the Apple TV, dates back to around 1995 and is based on a Mac from that era.
The model listed is priced at $600 (starting at $400) and seems to be an American model, with blocked SCART connectors.
It’s worth noting for anyone interested that this device requires a specific server to receive video—it’s not standard Ethernet.
