You can create a disk image using `dd` or download one from the `blank_images.zip` file. These images are compatible with the RaSCSI device and Basilisk II emulator. diff --git a/docs/assembly.md b/docs/assembly.md new file mode 100644 index 0000000..e6586d6 --- /dev/null +++ b/docs/assembly.md @@ -0,0 +1,53 @@ +# Assembly + +## Before you start + +Read through all instructions before starting. + +## Building + +1.
