nice job! rebuilding that PC baoard, complete with ic sockets n all. YOu're very lucky to have such a clean board n also parts that are still available. Thats a brand new power supply now. do you think that power supply can be adapted to the duel dicro? not all power supplies are created equal. the older systems have spider webs of wires n point to point instead of ribbon cables. Unraveling the mess is very tedious work unlike your very organized pc board. to make matters worse.. many old technology parts like that neon lamp fired vactrol optoisolator aren't available these days. substitution is slightly more complicated for a handy photographer DIYer. maybe not to a hobbyist or electronics buff. looking at 40 n 50 year old circuit boards, there are parts that have been so burnt in, you cant tell what they are. chard epoxy cover traces that go under other parts making them dissapear. that brown burnt flux complicates connections as well. then the can of worms, disintegrating lead based solder powdering so even after wringing out the circuit, it still doesn't work even though you replaced the burnt out parts due to a cold joint somewhere you havent checked or was disturbed while checking. once again, beautiful job on your rebuild. I wish all electronics were as clean.
