    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Yeah, I get over zealous sometimes. Nice PDF. I love vector graphics because I can zoom in on-screen and everything is still legible, rather than an unintelligent pixelated mess. For the final product, however, I'll need the pinout schematic in a form that makes drawing it in KiCad easy...

    my first Lisa

    All of these electrolytic capacitors have finite lifespans. The ones from the 80s are now at the point where they are beginning to fail. All of the capacitors will need replacing at some point.

    iMac G3 Won't Power On

    You can replace the fly back and transistors seperatly. Finding the flyback may be slightly difficult, but either DigiKey or Mouser should have the transistor you need.

    My First Quadra

    All three of these machines can have AV functionality. You just decide how you want to get AV functionality ;) .

    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Are you making fun of me? [:P] ]'> Just pretend that the silkscreens are swapped around. I already deleted the files off of my computer, they were a waste of space. I'm glad it's coming along nicely.

    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Really quick cheap dirty 3D mockup that took me only 3 minutes to make: I used 96-pin euro-dins as that was what was available in the library right off the top of my head. It gets the point across though. Also, the 3D footprint looks slightly shifted, but don't worry, it won't affect the...

    My First Quadra

    Well it's all about what you want to do. The nice thing about this machine is the MPEG media system!

    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Awesome. My preferred EDA package has a 3D rendering option. So, I can render a concept art based on a non-functional PCB design.

    ADB Keyboard and Mouse switch

    So, Revision A of the Analog video switching board for the project is complete. Now, keep in mind, this is revision A. By the time I start shipping these products, it will probably be at revision C (or higher). Anyway, it is provided by (74HC)4052s. Those are controlled by the microcontroller...

    My First Quadra

    Comparing the LC475/Q605 and the Q630 logic boards makes the 630 seem much more complex, like the 610 and 650/800. Of course the Q630 is a low-end Quadra, but it sure can bang out some great 040 performance. RE: the 610 case, I hate the front power button on it. It would be okay if you could...

    ADB Keyboard and Mouse switch

    Nice! This video switching is slightly different. It's all 4052s, controlled by a MCU. Five ports, 4 in, 1 out.

    ADB Keyboard and Mouse switch

    The first revision of the video switching board is almost complete. Stay tuned for some updates (and pictures!) tomorrow.

    Carboy7's conquests!

    If the capacitors have never been replaced... then Yikes!!! It might not be too far gone yet though!

    Evie's Conquests

    Hmm, that's unfortunate. There appears to be a label that fell off, perhaps that might have been more informative. May I ask, where did you get that drive enclosure, you mentioned it was 'affordable'?

    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Yup. I would love to put a 2nd PDS pass through too. Unimplemented for some people, or implemented for others. All boards will have the holes though for economies of scale (and for upgrading later if desired). I don't know if there is any sort of PAL work required to build a 2nd PDS slot, or if...

    ProtoCache1 - IIsi/SE/30 PowerCache Adapter Prototype Development

    Okay, well, I knew all about the whole 10cm*10cm being the whole ya know you explained it well. I just didn't expect the price to go up THAT much. Looking at it though, it looks like the 'normal' price for 10cm*10cm on SEEED is $10, so not as dramatic, but it appears to be permanently(?)...

    Disassemble the drive enclosure, and read the label on the top of the hard drive itself.

    Odd Quadra Motherboard

    I wish I could go there and pick some up!!!!!! Nice find! I don't exactly have a 650/800 case, but, I have enought parts to cough together a working system if I had the board. May I ask, how much per piece were they?

    Odd Quadra Motherboard

    Well cool! Nice find. Now all you need is a computer to stuff it in. I wonder if the ROMs might be a different revision then the final release ones?
