    Stuffit Magic Numbers

    I would recommend that you check out unar source code, which can extract Stuffit files (including resfork): https://cdn.theunarchiver.com/downloads/TheUnarchiverSource.zip

    SCSI to Ethernet Adapter on New Hardware

    Source code is up, so you can start manufacturing your own now. https://github.com/saybur/scuznet
  3. If you connect to another computer using a crossover cable or network card that supports MDI-X, you can disable auto negotiation to allow the link to work.

    SCSI to Ethernet Adapter on New Hardware

    It may be possible to do offloading similar to how A/ROSE did it. However, you would need to write a new INIT and/or adev for it.

    SCSI to Ethernet Adapter on New Hardware

    I'm curious if it's possible to make a SCSI port multiplier, or if it's daisy chain only. There's also the Scuzzygraph, which provides a display through SCSI. A device similar to that would be nice to easily add more displays. --- I'm curious if some processing is offloaded (similar to the Apple Ethernet NB card).

    Would this be any faster than serial?
  8. Use Disk Utility to convert to raw disk image
  9. File System Manager exists, which is the interface to add other file systems. I haven't really looked into it yet to see how you access and mount filesystems versus the FUSE interface. FatFs is an open source library implementing FAT file systems including exFAT. Also, the open source lwext4 library exists for ext2/3/4 file systems.

    SCSI2SD as an External HDD for Multiple Macs?

    You can use different SD cards with SCSI2SD. If you want to use one SD card, you can change the partition/drive mapping by usage of scsi2sd-util. In case of internal HDD failure, you may need to remove the internal HDD to avoid a delay in boot.
  11. Cross application communication could be done easily using Apple Events. Each application could run in its own Toolbox environment. It seems like Elliot Nunn is disassembling the Classic ROM.
  12. I know adding RAM to a 4•8 card allows it to operate as a 8•24 card, but what happens when you add RAM to a 8•24 card? This "chip" was very easy to pull off of the card. Looking at other images of the 8•24 card, I've seen plastic packages, but none of this kind. Was it a prototype card? (By the way, some pins were already bent before I pulled it off)
  13. I think it would be nice to start up emulating the Toby graphics card, since it should be compatible with most software including A/UX. About QuickDraw acceleration: What about emulating 68k code? It can possibly be quite a bit faster with little effort compared to reimplementing QuickDraw, and it could also work for other types of graphic drawing code like QuickDraw 3D or OpenGL.

    601 processor replacement experiments

    FPGA would be interesting. However, the Apollo core is closed source (because they are intending to manufacture it on ASIC), so an alternative method would be needed. It would be interesting to accelerate 68k on ARM processor. This exists: https://github.com/PandTomB/uae4arm

    SCSI2SD image editing

    Use losetup to create a loop device for the 2nd drive at an offset, then mount that. You can also extract the image for the 2nd drive using dd at an offset, make changes, then reinsert the image.
