I am thankful for an active community that enjoys helping each other learn, and today I am coming with an ask for help. I have a SWTPC 6800 and ADM3A terminal, I can get it to boot, and when it boots it will continue to boot for several hours. But getting it to successfully boot takes upwards of 100 power OFF and ON cycles. The other 99 times, I get a continuous stream of random ASCII characters (see video link below). It's my first time seeing this type of issue that happens intermittently, and wondering if anyone has any insights in what might be causing this. I suspect its a faulty IC on the Processor board that resets or controls the OS reset, will need to deep dive and diagnose, but thought I would ask for some direction first. https://www.youtube.com/watch?v=Ci4vhPn-3PE Thanks in advance! -Nick
