Seen on eBay for around a hundred euros, a prototype motherboard. It is intended for an Apple Workgroup Server (WGS) 9150.
This board features plenty of RAM slots, multiple NuBus slots, and a (blue) debug connector. Based on the markings, the processor is a PowerPC 601 at 120 MHz (Speed Bump), and the cache memory is 1 MB. You can also see what appears to be a Peltier module coupled with a fan.
