  1. Could be dried up caps. The cassette deck for my TRS-80 worked fine when I last used it in '86 but was useless when I tried it a few weeks ago. Of course the belts were shot but even after replacing them the sound was horrible and no data could be read. Ended up replacing every capacitor and it now works like new.

  2. Back in the day I gutted that RS amp and installed the PCB inside my Model III with its own speaker, power supply and on/off switch on the back. Just one of many experiments I did with it as a kid. For a home computer that technically had no sound, it pretty much blew away every other computer and game console at the time when it came to sound and clear speech. Big Five Software really knew how to get the most out of that line of computers.

     

    This year I decided to bring that computer back to life (owned it since 1981) and did away with the RS amp...always had a buzz and no way to adjust the volume.

    Most modern amplified speakers have no volume control but I found a nice one on eBay for $10 bucks. Volume works well with the line-in and it also has a FM tuner and MP3 player.

    Then there's the killer Orchestra 90 that goes to a set of PC speaker with sub-woofer.

  3. I'm the complete opposite. My arcade games are as original as possible down to requiring a quarter to play. The furthest I've strayed is a Clay's MultiPac kit which at least requires the original hardware and can be removed in 5 minutes.

    Just purchased a Harmony Encore so I can play games on my original 2600 without having to use some emulator.

    Emulators and Multicades (especially emulating pinball machines) remindes me of playing Tourist Trophy on my PS2 and selecting the Hayabusa vs. going out for a ride on my real Hayabusa...there is no comparison.

    And don't get me started on those who destroy a vintage arcade game by turning it into a Multicade. That's just as blasphemous as destroying a vintage Chevelle or Mustang.

    I pretty much got out of the collecting loop about 12 years when I felt my collection was where I wanted it and RGVC and RGVAC started to die off. Starting to get back into it and I have to say I'm a bit shocked at some of the viewpoints towards real hardware.

  4. With the foil tape, no glue is needed. It's just a mild pain to get the paper backing off the dots once they're punched out...an exacto knife helps.

    I've always felt the carbon pads were 100% at fault and not the flex circuits. When I used the copper resin, I had over 10 years of use without ever having to take them apart. That many years and countless hours of use was a good run but I think the foil tape will be far better.


  5. I would try crazy gluing bits of aluminum foil to the black dots on the fire buttons. This isn't usually needed for the keypad buttons... Just cleaning the metal contacts with alcohol usually does the trick for them. Good luck!

     

    Better yet, HVAC foil tape (not duct tape) and a standard paper hole punch. Takes about 20 minutes to do the entire controller and should last a lifetime.

    I originally coated the pads with rear window defroster repair resin back in the 90s but that started to fail after 10 years. That stuff still works well for bridging broken flex circuits.
