Disk Jockey

Disk Jockey is an application for macOS and Windows that lets you create disk images that work in devices like BlueSCSI, Floppy Emu and PiSCSI / RaSCSI, as well as in emulators like Basilisk II and Mini vMac.

The macOS version also analyzes images that either contain a single volume, or entire devices. It can show the contents of HFS, MFS and ProDOS partitions. And it can perform a few neat tricks like converting an existing image that works on Basilisk II into an image that works on BlueSCSI or PiSCSI / RaSCSI, or replacing your Lido SCSI driver by a classic driver that will improve performance in modern solutions.

All versions of Disk Jockey are free 🎉, but you can always buy me a coffee if you want:

Here is some documentation. As you’ll notice, Disk Jockey has grown a lot since #Marchintosh 2022, and so has its bag of tricks.

Pre-made images
