Yeah you're right. My bad. Too much vt's in my head it's kinda....confusing...lol

Just the crap that comes up on google.

I'm going to interpret that as a definitive, "I don't know."

Based on the lack of informative responses from VIA, Google, and this thread; I went ahead and coded up a simple parallel port bit banging I2C host adapter implemenation. I should get it tested with my CMPS03 compass module tomorrow. If all goes well then we will have officially changed direction (again) for the initial testing of our radios. The good news is, you won't need an M10k to test -- you won't even need to open your computer. Just plug it into a bidirectional parallel port and go.

Better get those boards fab'd soon Seth.

I finished testing it and the good news is, it works! I now have a low level I2C library suitable for control of our radio and signal processor ICs.
