I see that the XE is utilising the on-board audio facility of the southbridge (which I assume is still a 686B) and thus removing the need for the AMR slot.
There is a lot of free space on the motherboard.
Shame that the IDE/floppy/etc headers don't have the plastic surrounds, they are just bare pins sticking up.
Hmmm, I wonder where the 3COM network controller has moved to on the motherboard?
