Hi all -- I'm working on restoring a pair of Thinker Toys Discus/2D disk drives (8" drive enclosure with power supply, a-la: http://collections.museumca.org/?q=collection-item/20043152). I have the complete manuals for the controller, but I can't find anything on the drive enclosure itself; mine have suffered a fair amount of corrosion and rust (fortunately limited to the power supplies, the drives themselves are fine) and I'm trying to identify the voltage regulators the power supply uses but they're so far gone the markings are worn away. Anyone have a schematic for this? Bitsavers has the schematic for the original Discus, but not the /2D. Thanks in advance, - Josh
