    No, just grey wrinkle, like most of us...

    I see it's missing a couple chicken-head knobs.
    Parts swappers at work?

    That home-brew monstrosity came to me at a Yuma, AZ hamfest a couple years ago.

    It had a really sorry state of internal workmanship, so I stripped it for parts.

    The photo was taken when I got it home in situ.

    I hate when people cannibalize perfectly good equipment...

    In the late 70's we (my company and I) were building a digital radar processor. The processor consisted of four 6 foot tall 19 inch racks plus a control console. One rack for range and three racks for azimuth. It was all TTL, so it took two huge air conditioners to keep it cool. There was a power supply in the base of each rack that that provided 10 Volts at 500 amps. In the azimuth section there was a circuit card that was labeled "Non-Accessible Memory".

    That was actually a memory board that was made from 1K bit shift registers. The data was written in serially, but you could only read the data at 1K increments. The rest of the data was "Non-Accessible" until it was shifted out.

    Did you ever figure out what it was or what it was supposed to do? Looks like a good collection of parts.

    Excerpt from Wikipedia:

    "The original technical description of the "turbo-encabulator" was written by British graduate student John Hellins Quick (1923–1991). It was published in 1944 by the British Institution of Electrical Engineers Students' Quarterly Journal[2] as also noted by consulting firm Arthur D. Little in a 1995 reprint of Quick's description, and giving Quick's full name.[3]

    The earliest written U.S. source may have been in 1946, in an Arthur D. Little Industrial Bulletin. An early popular American reference to the turbo-encabulator appeared in an article by New York lawyer Bernard Salwen in Time on April 15, 1946. Part of Salwen's job was to review technical manuscripts. He was amused by the technology and passed on the description from the Arthur D. Little pamphlet.[1]"

    From all appearances, it was a ch. 2-13 television. With a lot of jewelry on the front that wasn't hooked to anything.

    The two CRT's were one for image (short persistence), the other for some sort of measurement like video level or baseband. It did have a real Hi-Fi audio amp after the demod, and a 12" full-range speaker.

    The chassis (2) had many holes, sockets with no connections, and really sloppy construction overall. Whoever it was, they did have good panel-making skills.

    The second video from Keysight on the Encabulator is even funnier, assuming you watch the first one first.

    Their lawyers got ahold of it and cleaned it up.

    Encabulator fans likely already know this, but there is an occasionally funny subreddit called VXJunkies that keeps the spirit alive.
