Neither of the NTSC boards ditched the WCS (unlike the PAL mobo). I may have a rev 6 and an A still if you'd like to purchase a known good and fully working board set. Not sure what the difference is between the two, other than A having copper traces and 6 having silver/tin. Was about to list one or both soon on eBay anyway. Can also sell with IC's removed if you want to save a few bucks. PM if interested and in the States!
