Re: Omega Race

Well Long test turned up nothing.

However. PB Junkie might be correct. I pulled the 5101 and It's no longer in
a constant state of reset. Now it will reset every 6 seconds or so. But I'm
seeing some output on my O-scope now!! WOOT. Making some headway.

Thanks Mike..

I'll keep digging and see what else I can find.
