He used to have that video on his website - which I've discovered via a Usenet discussion not too long after it happened. It was one of the first videos I've downloaded via a web browser, and almost certainly the first video made with a digital camera I've ever seen.
"Looking at Goble's video and photos, I became, as an American, all choked up with gratitude at the fact that I do not live anywhere near the engineers' picnic site."

Well, now I know what we should be pouring if anyone plans to use the expression "pour one out for…"
George was a really interesting guy, a true hacker's hacker, and I truly enjoyed talking with him.
The problems of conversion include in/compatibly of lubricants and refrigerants with seals and the density, boiling points, and latent heat of vaporization of replacements. The R-12 to R-134a conversion process was simpler but typically included different lubricants, orifice, and o-ring seal materials. I don't see how R-12 to a hydrocarbon or admixture of R-290/600a isn't a magical tall tale without proper math, equipment, and understanding of HVAC operating principles.

I am glad to have been 100s of miles away.
Thank you for your work, and of corse for the many many laughs.
Almost everyone and everything around us of any importance is one mishap away from going disappearing in a hot, sooty flame.
(it's a great book in general, but the bit about our use of a volatile gas for a living environment is pretty neat)
Amazing. RIP.

I worked for a George as an undergrad too, between Housel and Longshot. Went to many a lunch at Pizza Hut, Pepe’s, and Burger King (“run it through the broiler twice”), usually riding shotgun in the Pontiac Transport.
I didn’t do much on the NP1s for George. By that time Gould had been folded into Encore and development on the NPL architecture had been halted. While the NP1s were still key resources at ECN, a lot of our attention shifted to the Ardent Titan by then, and trying to shake the bugs out of that machine and associated software, including a port of an early version of Matlab.
George was a true renaissance engineer who set an example for me to follow my curiosity and not worry about sticking to a single, narrow field. As a result I’ve had a wonderful career that has included supercomputing, computer networks, land mobile radio, software defined radios, telecommunications, electric power, and rail transportation. Ironically, I have never been all that great of a programmer, but I feel the year or so I worked for George really opened my eyes to what being an engineer could be. I’ve tried to pass that on to the engineers I’ve mentored over the years.

I see now, this is described in the Wikipedia article as well.
"This model is essentially a copy of the "dual VAX-11/780" computers hand built by wire-wrapping the backplanes of two VAX-11/780 CPUs by then graduate student George H. Goble and undergraduate assistants at Purdue University as part of his work on his master's degree thesis on modifications of the Unix kernel for multi-CPU architecture."
Yes, he was the first. DEC had made a bunch of attempts, he got it to work, and DEC came running.
