The last time I checked (last year) the eval boards

chips were rather expensive for the hobbyist. It'd be cheaper to pick up
a Crusoe-based laptop mobo or machine, and use that for a possible
platform, altho I'll admit that it's certainly not the *ideal* hacking
platform available. Sometimes, one must balance function with cost.
The principal problem with such a project is that the VLIW architecture
is not publicly documented, nor is the source code to CMS available. It
is treated as "black box" microcode from the customer's point of view.
That's really too bad, as we had quite a few neat hacks internally.
It's an odd feeling to have a debugger open on a CPU's "microcode",
though it more closely resembles an OS kernel or a very large device driver.
