  1. By "sample" do you mean "recording"? As discussed previously, it makes far more sense to me to synthesize the audio with a DSP. On a Mac SE, Classic, etc. there is little to no difference in performance between an HDD and a SCSI2SD due to the 53C80 controller being so slow. For a machine with a faster scsi controller, only a representative sample of operations would be synthed. The firmware would have minimum and maximum lengths for synthed seeks, reads, and writes based on real scsi drives. If the operations are too fast, then it would discard operations to meet the time constraints. Another option might be to slow down the flash speed for a more realistic retro experience.
  2. I have pivoted the project in a different direction. Keeping quiet about it until it's ready, because knowing me, it could be a while.
  3. If one follows the suggestion to use netatalk, then the resource forks are just extra files. You would just commit the resource forks like any other file in git. It does mean though that anyone using the repo would need to have a way to do the reverse operation. There's probably no way to avoid that.
  4. It's almost the same as USB Wombat. The primary differences are : * ADB Busboy has 2 USB ports * ADB Busboy only allows you use USB peripherals on ADB computers, not the opposite. * ADB Busboy has better power protection between the ADB host (computer) and USB bus.

    Massive PC/XT/AT & Apple II haul

    This site looks like it's dead now. Maybe they need to pay their hosting bill.

    LCII Buggered C14 plus side...

    I just pulled out my LC II and verified it against the real board too.

    LCII Buggered C14 plus side...

    According to the BOMARC schematic, C14 is connected to pin 7 of UB9.

    Macintosh IIsi

    The eyes follow the cursor around and occasionally blink. That's all they do. There were a lot of silly programs like this back then.
  9. A related topic came up in IRC today so I figured I should really post an update. I solved the unreliable behavior with daisy-chained hubs. Some USB devices draw a lot more inrush current than others. Adding a capacitor to each port solves this problem. I redesigned the PCB to be about 40% smaller, switched to an RGB status LED, upgraded the ESD protection diodes, and probably a couple other things I have forgotten about. I haven't ordered this new board yet. I want to review the layout again first. When I will get around to doing that, I don't know.

    Board Cleaning - Techniques - Chemical Reactions

    I did the litmus test a while back. I decided that vinegar was the appropriate opposite pH range, so the goo must have been alkaline. I only did one sample, so YMMV.

    Board Cleaning - Techniques - Chemical Reactions

    Ultrasonic cleaning is definitely the way to go. Wish I could afford one large enough for logic boards!
  13. The photo on the AllMacs ebay listing shows that they used through-hole capacitors. Not a good sign, IMO.

    Adding Wi-Fi to my Mac SE/30

    This is a really good write-up. Nice project! The access point switcher should be fun too.
