It's actually where some of the chips will only work consistently under 
7.5V and others refuse to work below 7.7 V.  It's seriously that bad!  
In my Solina diagram it had said resistors were adjusted to get the 
voltage optimized so that's what I did before but it didn't last 
somehow.  I've never seen such a stupid finicky bunch of parts as I 
somehow got here but..then again they seemed to be like I say more 
tolerent..the several I checked..in the Organizer 2.  Wow.    Well I may 
have to bring the voltage down there and sub in chips that will work 
that low since I absolutely can't seem to find any more that will work 
above that.  I briefly had them all working then one warmed up and 
cracked up again.
