Tell me on the electrical engineering bonehead scale 1-10 what you think of this shielding (w/ makeshift sielded bag): http://vintagecomputer.net/digital/PDP11-05_BA11-K/RAM-CPU_shield-bag1.jpg http://vintagecomputer.net/digital/PDP11-05_BA11-K/RAM-CPU_shield-bag2.jpg http://vintagecomputer.net/digital/PDP11-05_BA11-K/RAM-CPU_shield-bag3.jpg The bag ends folded over as they are shield between the back of the core and the inhibit board AND shielding between the back of the M7261 CPU card and the M930 bus terminator. I could cut the bag into two parts if anyone is concerned with air flow, but I bet it will still flow to the cards. Power on?

Thanks Dave.
I only have failures of bits flipping on, I have never seen a bit erroneously flip to off.
I have traded out all cards, no changes detected surprisingly. .. so your power supply ripple suggestion makes sense.

Also see what shielding can do. This morning there were no errors after I turned the system from its side to a position flat on the table.
