The other board was just fine. Also a system from a complete kit that I built doesn't have the problems either.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5237845887111894190.post-15600811483661208332010-07-17T17:05:47.411-04:002010-07-17T17:05:47.411-04:00Thanks for the notes John - you got me interested ...Thanks for the notes John - you got me interested so I dug out my Obtronix (kit) and verified that there was a trace between D7:7 and D7:10. The trace is clearly visible on the top side of the board and ohm-meter verifies continuity between the pads from the bottom side of the board. My Obtronix board is labeled Homebrew 2005 in the solder layer on the bottom side of the board (above the "Apple Computer 1" logo, which of course is on the top side).jackrubinhttps://www.blogger.com/profile/13091545068429541480noreply@blogger.com
