Here's a Dyna mechtronics machine just like mine, this one  is abit cleaner.. ok way cleaner than the one I got.  Mine came out of a graphite shop.  Black dirt everywhere.  It's a nice garage machine, weighs approx 3500 lbs and the top spindle speed is 4000 rpm.  Alot of fun, but the control blows chunks.  It doesn't take a standard G&M code it's abit odd.  I'm planning on doing a retro fit on the unit and run Turbo CNC from Dak Eng. on it.  You can find them at www.dakeng.com .  They have a TON of info on CNC equipment and retro fits.
