    I love watching your videos of Amiga repairs, even though I can’t do this kind of stuff myself. I got a new Amiga 600 in 1993 and I still have it. I had it recapped by a pro and I also put some new parts such as Furia and SD/IDE adaptor in it. I still use it almost every week after 30 years. I never got an Amiga 1200, but I think I can live with the good old A600. Thanks again!

    With retro brighting it can be fiddly job, my last a500 went well with no streaks, but the A600 i did get was so yellow I had to go back two times and redo parts. depending on the if used gell or the water based stuff and being the percentage all so plenty of good sun/light it will eventually get a good result. good to see another Amiga saved

      @@JanBetaOk, lets say it's complete as far as my use case goes... At least two of my A1200 just has a terminator on the internal drive header, for fast boot... I use an external drive when needed. :) That miggy just needs an '030 accelerator with some Fast Mem, or something along those lines. Looking forward on diagnosing that nonworking expansion.

    A good tip I was given for a broken key stem is to use a toothpick. The diameter is a near perfect fit for the hollow part of the stem. Just cut the toothpick to the right length and this will provide the added stretch you need. In my case, I used a little epoxy in the hollow and around the outside of stem. The key fits fine and is still holding strong.

    • @JanBeta

    One thing I want to try with rusty shields is to soak them in Evaporust. That stuff is amazing and should give great results with much lower effort than the fiberglass pen.

    • @jonhoyles714

      you could try a air line with a bag full of sand and drip feed the sand into the air stream to clean that rust

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน +1

      I definitely need to get myself some of that miracle stuff. It's been recommended a lot recently. I tried cola and aluminum foil a couple of times which worked pretty well but Evaporust seems to be a lot more versatile than that crude hack. :)

  • @screamingattheradio
    @screamingattheradio 8 หลายเดือนก่อน

    One thing I've done on a broken cap on an Atari XE which had the same footprint, square with the little hole in the middle, is to use heat to insert a small metal rod into the little hole (I think I cut a paperclip), all the way so it ties the broken stem back to the rest of the cap. It provides the stability that glue won't.

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน +1

      That makes sense. I'm going to give that a shot (in case I didn't mess the keycap up completely with my repeated glueing attempts...). Thanks for the tip! :D

  • @mikedefoy
    @mikedefoy 8 หลายเดือนก่อน

    For all my repairs, I use JB Weld, a 2 part epoxy with a clamp. This has proven to have been superior to all other products. The trick is to use the clamp and apply the material to both sides. As far as retrobrighting, the best result is suspending the items above the peroxide in a sealed container out in the sun. The vapor gives a uniform finish and the solution never touches the item.

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน

      I used similar epoxy glues and they usually work very well. Might be another option to try in this case. I don't have much room, that's why I didn't get a large container (plus gallons of peroxyde) yet and still use the cream method. Also, sun is not quite powerful enough here in Germany. :D

  • @wheelycrafty
    @wheelycrafty 8 หลายเดือนก่อน +1

    CA glue forms a brittle connection between the parts being repaired and can be broken quite easily, if you have space sprinkle some baking soda on the glue before adding the kicker it will make a much stronger joint. For repairing plastics, cracks especially I use something called Plastic Weld. This must be used in moderation as it actually melts the plastic on both sides to join them, a single tiny drop should suffice on both the cracks to your case and the the broken key as it will wick along the joint until the joint either ends or meets itself. I still have a nearly full bottle I first started using around 20 years ago it seems to last forever lol

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน

      The glue I used the second time around is a plastic welding glue (mostly acetone based, as I said). Usually that works really well. Should probably have used it the first time around but I didn't want any deformation (which is risk with those weld bonds).

    One word to the "Glass Fibre Pen" (Glasfaserstift) - just be a bit cautious, because this stuff (the microscopic glass parts rubbing off) can be very unhealthy, when breathing them into your lungs. Don't clean by blowing them into the air or rubbing off with your fingers. Your health is very important, just because we also need much more videos from you... ;) ... So please stay healthy.

    The coprocessor expansion board looks like it needs a clock chip (rectangular metal can with 4 pins). Probably same frequency as the one on the main board. The dead giveaway is the socket with 4 turned-metal socket pins near the FPU. 😌

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน

      I did some research and got it to work in the meantime. It's quite an interesting board, actually. You can add a quartz oscillator in the location you mentioned to run the coprocessor asynchronously at higher clock speeds or just set a jumper to run it at the system's clock speed.

    Hi Jan. What about cleaning (and retrobriteing, if needed) the “U” key from the other keyboard?

    • @JanBeta

    Wonder if glueing in something like a toothpick in the center bottom of the key then glueing the broken stem to both the toothpick and base of the key would work or does the key need to have the hollow space. Also the Amiga is looking really good for its age i think anyone who loves these machines would love to have it on their desk ready to go. Great Job.

      Oh, it's an old LG TV. It has a SCART input but I mostly use a cheapo upscaler box and the HDMI inputs. I wouldn't especially recommend this setup (I only use it for testing, the lag is quite horrible, so not really suitable for gaming and such). The TV is just there because I got it for free (it was broken and I fixed it) and it just fits the spot above the workbench. :D

  • @psteier
    @psteier 8 หลายเดือนก่อน +1

    Still recommending not to retrobright with that creamy stuff, better use fluid peroxide and submerge the parts. Yes, you will need a bigger bin and yes, you'll need some liters of peroxide, but it doesn't make any marble and stain effects, is more effective and secure. After all, the yellowing will come back in some years, the most better way to have it (in this case case) white again, is painting it...

    Einfach nur Acetone und ein Pinsel zum Aufstreichen. Dann wird das automatisch verschweißt und die Verbingung ist wieder wie neu. An der Stelle bricht es jedenfalls nicht mehr. Am Besten mit gerolltem Papier in Position halten. Mit Acetone ist der Kram in Minuten fertig und nutzbar. Hätte auch beim Lüftungsschacht funktioniert, sofern das ABS ist, wovon ich mal ausgehe. Da Acetone sehr flüssig ist, läuft es auch in die Ritzen und am Ende ist es wieder ein Teil.

    • @JanBeta
      @JanBeta  8 หลายเดือนก่อน

      Der UHU-Kleber, den ich zuletzt im Video versucht habe ist so ein verschweißender Plastikkleber (größtenteils auf Aceton basiert). Bei der Taste wollte ich vermeiden, dass sich das Teil verformt und habe deshalb zuerst Sekundenkleber probiert. Beim Gehäuse macht der verschweißende Kleber mehr Sinn, hält aber bisher auch so. :)
