    AppleCD 150 can't read CDs

    This is a common problem with caps: http://www.asterontech.com/Asterontech/next_cdrom_refurb.html

    LC 475 Chip Corrosion: When Standard Methods Fail

    Says me, but I guess you're welcome to disagree. I had mixed results before switching to a Crest. That aside, even a cheap Chinese model is probably a lot to justify for a single repair.

    LC 475 Chip Corrosion: When Standard Methods Fail

    An ultrasonic sized for logic boards is probably too expensive for a single use. You need a sweeping frequency model to do any real work and those are priced pretty high. I would drench it in liquid flux and apply new solder. Then just clean with alcohol. That should fix a localized area without too much difficulty.
  4. Is it just getting power from the bus? I don't see anything about connectivity inside the apple II.

    SE/30 - ceramic recap causing distorted audio?

    The ceramics themselves should be totally fine to use. There are debatable thoughts about the long term effects, but for this use they are functionally equivalent. The solder job looks ugly though. I would also suspect that the board was not properly cleaned.

    Quantum ProDrive Rubber Replacement

    I've used a few o-rings stacked with success. I have links here: http://www.asterontech.com/Asterontech/Quantum_ProDrive_40s_Restore.html

    AppleCD Plus M3021 won't mount cd's and cd-roms

    @bushok The connector should be fine. Just clean it with a qtip. @techknight Yes, the original SC drive is way more complicated to work on. So many connectors...

    The flat ribbon cable is the only one to be really concerned with breaking. The yellow cables just use a firm grip and rock side-to-side a bit.

    Yeah, the black discoloration on the back side is due to the capacitors leaking. The board otherwise looks in OK shape, so you probably have a high chance of success.

    I've done about a dozen of these and only had one bad laser assembly so I guess I'm bias in the other direction. The good news is it only takes a few minutes open it up and confirm.

    It could be the laser, but I think is more likely caps on the logic board. See my guide here: http://www.asterontech.com/Asterontech/next_cdrom_refurb.html

    ProtoCache1.1 - IIsi/SE/30 PowerCache Adapter Prototype

    Awesome work! Count me in for one of each. Any interest in selling kits or bare boards?

    New Lisa Hardware Coming

    In this case I imagine their production costs are probably really high selling fully populated boards. Maybe in the future they may consider selling bare boards, but unless you have the parts on hand that quickly gets expensive as well. A team of 4 essentially recreating the entire machine (outside of CRT of course) is awesome. Nobody gets rich from vintage hardware, and I suspect there's no way they will recoup the time/materials they spent on this. Real engineering hours are -not- cheap.
  14. Wow this is really cool! The direction you're headed this could easily become an all-in-one solution for any vintage machine.
