Re: Real time operating systems

I have no experience or expertise to say whether your idea would work, but
off the cuff it sounds like it would be more work than it is to just load
Linux and get EMC running. I think with the help and support of this group
someone could get Linux and EMC set up and running in a couple of evenings
and from that point on the Linux portion becomes pretty transparent and you
just deal with EMC.
