2. When I was in elementary school back in the 60s we had huge asbestos curtains in the auditorium. We were told if there was ever a fire to wrap it around us to protect us from the fire, LOL. Then again they also taught us to duck and cover under our desks to protect us from exploding atomic bombs. That electronic calculator reminds me of the first one my Dad got in 69 or 70. The company he worked for provided it and he said it was like $280 and did add, subtract, multiply, divide and I think percent. In 76 I bought a scientific calc for college and it was $30. When I replaced it several years later the same calc was $9. LOL. Wise words on asbestos. Don't disturb it and you are fine.

3. The romans made quilts out of it used in certain group gatherings and would burn them afterward to clean them,, There is a roman poem that speaks of "Short is the life of the quilt weaver"

4. Seeing the inside of this made me terrified for all the countless people who were exposed to asbestos in that plant. So much suffering due to negligence by the people who ran these types of facilities. My grandfather worked in an industry that was only tangentially related to asbestos and he recently passed due to mesothelioma.

5. HA! Just in time for my pasta to get ready on the stove! Thanks for planing this, Fran haha! 😀
   Some people take "no serviceable parts inside" as a challenge … or so I've heard …
   You better be cautious with the dust from that thing asbestos you can !!!

6. My test of vintage: Try to divide by 0. The result tends to indicate the sophistication of the ALU. Also, the inventory tag indicates that this was a capital asset in its day. Geezer fact for youth today.

7. Asbestos is nasty stuff. That's what took my grandmother in the end, simply from washing the asbestos laden overalls of my grandfather who worked in a shipyard. It didn't show up until her late 70s, by then it was too late.

8. They appear to be hair and dust that is commonly found on old or greasy components. Did Metalbestos use it in everything they made, If so, what is their intended purpose, to insulate?

   A little known fact, that the twin towers were basically worthless due to the many millions of dollars in asbestos removal costs that any buyer would have to pay in order to lease the office space. Nobody would buy them, but then someone did and had them insured against terrorist attacks for 3.2 billion dollars, 6 weeks before the "attacks" happened.

9. For safety, simply use a vacuum with a filter for clean-up and place your toys behind a glass or plastic shield while you film. Asbestos isn't the only dangerous substance you are likely to encounter given the wide variety of old equipment you take apart. Maybe you could build a simple fume hood to quarantine your ancient artifacts during examination.

10. I love those displays! My grandparents had a calculator that used them, and it brings back memories. I like how neatly routed the board is, even though it's obviously been traced by hand.

11. [ The useless information of the day ] The word asbestos is a Greek word literally written with English characters ( ασβεστος ) and ( in loosely translation ) means: "the one that never burns out", "the one that keeps burning forever" ! It is the a- in the beginning that means the exact opposite of the following word and the -sbestos from svistos that means burned out.

12. There are 'neon signs' that are adaptations of the panaplex display!
    [I know, I know…. panaplex used surface glow on the electrode, these are more like neon tubing in a box!]
    [The main similarity is a flat-package, self-contained glow discharge display]
    Glowing gas discharge is constrained by glass and ceramic elements to form pretty pictures.
    Three panels: top glass, 'art layer' and background.
    The 'art layer' and background are machinable ceramic, top glass is glass.
    The background is drilled for electrodes and filling ports, then bonded with frit* to the art layer.
    The art-layer is milled to create passages ( 3-8mm wide) from one electrode to the next, forming a discharge path.
    Rather than bending glass tubing to make letters, use a router!
    After cutting out the channels, the top glass is installed, bonded with a lower temperature frit than the first.
    After bonding, the panel is evacuated, back-filled with Neon.
    Often the top-glass had its own design elements that the glow enhanced.
    Some top-glass had fluorescent coatings to proved pastel colors!
    Being that these were cheap, mass-produced "OPEN" or "Miller Lite!" signs, nobody seemed to care about longevity, so no getters.
    It was quite rare to find custom designs in this type of signage!
    10-15 kilo-volts, very low current.

    These were showing up about 15 years ago, but LED's in plastic covers took over that market.

    *Ground glass in a low-temperature glaze. Re-flow solder for glass!
