DEC PDP-8/e Omnibus backplane lubrication

I've been successfully using Deoxit and related products for many years, after I learned of them from government projects where I was a consultant. In a specific case: My PDP-8/E has 32K of core memory in four banks (original DEC). Several years ago, it developed random memory errors. I did all the usual things - made sure the OTT connectors and edge connectors were clean, that there was no observable "dirt" in the back-plane, etc. I reinstalled the memory - and it worked - for a while. Then the random error returned. Not often - but often enough to be irritating. I then used (sparingly) "ProGold" (now Deoxit Gold) on all the edge connectors. After re-installation, the memory was "perfect" (no diagnostic errors). Now some ten years later, I've never once experienced another memory error on my PDP-8/E. That was enough to convince me empirically that the product worked as advertised. Ever since that experience I've used Deoxit Gold on many pieces of test equipment and vintage computer gear and have never experienced anything but good results.
