An update on the Topcon MDA monitor is coming soon. Until then, here's some pics of the Commodore CM-312, looked pretty good from the outside, however inside.... Things were off to a bad start... corrosion and dust everywhere and a film capacitor had split open... The cause of all this decay is one of the 200V mains caps in the power supply had gone bad, rupturing its corrosion inducing electrolytic everywhere. I've never seen one that bad (or lumpy) "We can rebuild him; we have the technology"
