[vcf-midatlantic] Core memory

Getting intermittent stuck bits with my pdp 11 non parity core stack.
Without getting into a lot of detail, I noticed that something is causing
the inhibit to fart high every so often, effecting address bits and to a
lesser extent data bits.

I have been doing a lot of research.

My question.. aside from manuals and the tech docs does anyone have any
anecdotal info, advice or test procedures related to DEC core RAM and
intermittent stuck bits?  Shielding tips?
