Heh, I must be getting better then 8) I answered that one in some follow-on mail on the subject - I should have mentioned it up front. Personally though I'd have been more worried about the inductance of the relatively thin wire in the ribbon than mutual inductance, given that there are ground conductors either side of TERMPWR. Regardless, it's the best way to go. > Rod Grimes rgrimes@gndrsh.aac.dev.com -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
