I saw the title and was going to comment about the same thing. My understanding is the GA144 is clockless. From the product literature the advantage is reduced power consumption. It is also a Forth machine.

I've wanted to get one of these for a while but the eval board price is a little steep for someone who just wants to tinker with it. The chip individually is not terribly expensive. At one point there was a budget version available for around $20 but these are no longer available.
