BlueSCSI Images

Below is a list of validated BlueSCSI images. They will work on BlueSCSI v2 or v1.


Premade Images

Premade images are handy to just drop onto your SD card and go. Use one of these methods on your modern machine to transfer files & software from places like the Macintosh Garden to your vintage mac.

Custom Disk Images with Disk Jockey

Disk Jockey is a free application for macOS and Windows that allows you to create disk images of any size. It can create simple disk images, and more complex ones with multiple partitions (HFS and ProDOS).

Custom Disk Images (Advanced)

You can also create empty disk images on the command line.

The following instructions demonstrates the process using dd on a modern Mac:

  1. Open terminal.
  2. The following command will create a blank disk image. You can modify the command to suit your use.
    • dd if=/dev/zero of=example.hda bs=1m count=500
    • NOTE: On Linux systems, if you receive the error dd: invalid number: '1m', you need to capitalize the ‘m’.
      • Example: dd if=/dev/zero of=example.hda bs=1M count=500
    • The count field defines the number of megabytes (bs=1m) the total disk image should be.
    • The output file from the command is “example.hda”. This can be changed in the of=example.hda field.
  3. Place the new blank disk image in the root directory of your SD card.

Format HFS for Macs

  1. If you do not already have a tool to format SCSI drives, download Apple HD SC Setup.
    NOTE: You can use an emulator such as Basilisk II to move files to the image to prepare your installation, but not to format.
  2. After booting into your target machine with the working Mac OS disk image on your BlueSCSI from step 3, format the blank disk.
