XORRO Prototyping Board fitted in an Amiga X-1000 Nemo Main-Board

Yeah what a waste of time, energy and money hey...Trev what were you thinking!

Not a waste of time, energy and money at all. What you're seeing is a prototyping board (veroboard style) that they have populated with a few buffers and LEDS, just to confirm that it's working. Flashing LEDs is a hardware developer's (and embedded software developer's) equivalent of "Hello World!" This is also the first thing that I do when I'm working with a new micro-controller.

Why does the X1000 require a second XMOS to perform this demonstration? Does the onboard XMOS not work?

The "second XMOS" is called an XTAG-2 debug adaptor (debugging via the JTAG port). It's not doing the work, but it is helping them with debugging any problems. Once the software is done for AmigaOS 4, debugging will be possible directly instead of via that device.
