A prototype of a Macintosh mouse

A $1,000 Mouse, Anyone? On eBay, there’s a prototype of a Macintosh mouse listed for that price. What makes this mouse special? It has an angled connector instead of a straight one.

Instead of the typical straight serial port, this mouse has an angled connector. Back in the days of the first Macintosh, ADB or — obviously — USB were not yet in the picture, and the first mouse still had a DB9 connector, commonly used for RS232 ports.
