In this episode I take a look at this old Commodore Calculator from 1972. It has a total power failure and some of the keys don't work.

    Your teacher made a sound judgement based on the information he had available at the time with the intention of turning you the most capable and independent. Sounds like someone who cared about you and your future. Unlike the people, and maybe yourself, who want some bizarre satisfaction from getting back at him. I suppose no good deed goes unpunished.

    I found a similar PET with a keyboard problem, and after some AltaVista-ing (this was many years before Google) I discovered that the solution was to use the blue end of a pencil eraser on the metal contacts under the keys. That seemed to clean them up enough for the keyboard to start working again. The scary electrical arcing noise coming from the back of the CRT was another matter...:)

When in fact his was a TRS-80 Model 2 I believe.) It was a genuinely great feeling watching him react, get sentimental and tell me stories about his 8-bit days (Like as a late teen early twenty something financing through his credit union his tape drive) thinking back to his days of tape drives and early floppy drives. I want you to know the connection that is reaching from at least in this case of two nerd borns in 1961 and 1988 respectively. Also and I have no right to request, but I could only imagine the joy it would bring both to recall the days of his youth and the joy it would bring me just watching his reactions. I you could do any videos involving the TRS-80?

    8:03 - I'd recommend buying a box of isopropyl alcohol wipes. I use them all the time for cleaning corroded connectors. I usually get the small "Prep pads", the same stuff that nurses use before giving injections. They're small, easy to open and quite cheap. You can also use lens cleaning wipes, though I think those have lower alcohol content. But those are better for cosmetic cleaning than the prep pads.

    My guess on the mysterious DOA repair is that the contacts in the power switch itself were probably oxidized and by simply mechanically flipping the switch a few times you cleaned it off and it began working correctly.

    It's very common. Foam rubber breaks down over time, as it's biological plant-based material (most don't realize this as it seems so artificial, but it's really not). There are synthetic foams that last longer but they're more expensive. "Standard" foam is only good for about 10 - 15 years before it falls apart.

    MrJest2 plant based? What's the name of the material? Today they use polyurethane foam, and it doesn't last worth shit, and it is fully synthetic, so there's that, the minor surface oxidation and halogen-based fire retardant eat it up. I actually think cellulose acetate foam lasts a lot longer.

    I took out the heater matrix of my 1972 Hillman Avenger a while back, which was covered in just the same foam where it is mounted up to the air ducts inside the dash. Disintegrated foam everywhere. I replaced it with draught excluder foam. The car also uses some of this newfangled silicon technology in the rectifier diodes of the alternator. The white heat of technology was really starting to happen in 1972.

    +Siana Gearz - Older foam is latex based, so it's made of sap from the rubber tree (plus catalysts and foaming agents). Around the time this came out, polyurethane foams were also starting to become available, but they were more expensive (and also break down when cheaply made, due to the organic component molecules oxidizing). This sample could be either, but my bet would be on the older cheaper version.

    There's not that much difference between the calculators from that era, and the home computers from a bit later on.

Very risky idea, this could be ground referenced to the neutral pin, but because there is no polarity on the plug it could also be referenced to the live pin.
