I heard some time ago that T12 HO lamps weren't being phased out yet.. Just the F40 & F96.
Universal Triad Ballasts have the wiring diagram on the label of most of their stuff... They're still selling F34T12 lamps and ballasts out where I'm at. I have started converting a few troughers over to T8 as the ballasts go out. But T12's are still widely available here from supply house to True Value.
