[Coco] Any news on the so called CoCo4 or Next CoCo project that Bjork was heading?

Hi Aaron,

The only reason I would have is "lack of desk space"

If I could build a DE1 into a laptop (eeePC?) style case, I'd be happy, cos 
then I could take it anywhere. But then drivers for an LCD would need to be 
done.

Hmmmm
