Unless your storage is very dry and clean, I'm afraid you will find that the problem
returns if you don't protect those pins/sockets with some sort of electrical grease.

Thanks for the tips everyone! I can confirm power is
GOOD, and the
problem persists even without the RAM installed (Just CPU and MP-C or
MP-S board). I am going to clean the buss connectors and see if it
helps!

Hey everyone, Happy New Years! 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.
