RE:New project...PCI based servo control board

[rehenry-at-up.net]

Hi Craig

I didn't even know there was an arm here to twist.  Thanks for the intro and the interest in the Sunday/Monday sessions.  You are more than welcome.  I'm certain that with the recent interest shown in hardware solutions to the servo problem, there will be a great deal of discussion that aims at the heart of the project that you have there.   

Anyone with an interest in the future of the EMC -- even the newbie's newbie is welcome to attend and speak up.  I'm certain that there will be brainfood for all.
