i too, need the manual for the ms8147c. matsonics website is either not there, or has truly been hacked and not updated. thier copywrite is still 2009 on the webpage and is reportedly an attack site. i would advise all windows users looking for this manual to stay away from thier site. ;D i dont care though since i use kubuntu. the power pins are unmarked as to allocation. im in no hurry since i still await the arrival of a PCI nvidia video card to use ubuntu server. thanks.
