Setting up your vintage (classic) 68k Macintosh – Using Basilisk II

You probably know what Basilisk II is, but if not, a quick summary: Basilisk II is an open source emulator for 68k-based Macintosh computers that support 32bit memory that runs on Windows, OS X and Linux (also works on some other platforms). Running Basilisk II on a modern system will allow you to make changes to the minimal disk images I have on this site before you copy them on to their matching floppy disk (or floppyEMU), Iomega Zip Disk, CD-ROM, or SCSI2SD SD card.

Because Basilisk II is already well documented on sites like Emaculation, I’m only going to describe the basics of how to use Basilisk II to add or remove files from the disk images available to download on my site, to help you setup your 68k Macintosh.

Step 1: Download and install Basilisk II

The latest versions for Windows, OS X and Linux can be found on the E-Maculation Forum.

For Windows, you need a combinations of downloads: the BasiliskII.exe file from the 2015 build and the complete Basilisk II application from the 2010 build located on the internet archive and the GTK-runtime environment.

Step 2: Download and select a ROM file

To run Basilisk II you’ll need a file containing a copy of the ROM from the 68k Macintosh System you want to emulate.   Luckily, the macintosh repostiory has made them available to download.  I personally use the ROM image I generated from my LCIII using the ROM dumping utility bundled with Basilisk.   I believe you must use a ROM from a 68k System that supports 32bit memory.  Basilisk II comes with a program called Basilisk II Gui that you can use to setup Basilisk, the basic instructions from Emaculation can help you out.

Step 3: Get or create your startup disk

If you don’t already have BasiliskII setup and need a startup disk image, I suggest using the minimal System 7.5.5 Iomega Zip Disk image I created to get you up and running.   This image includes a minimal version of System 7.5.5 and several utilities that will help you install files under Basilisk.

 

Step 5: Download the Disk image(s) that you want to modify or copy from

You can download image files for floppy disks, floppy-EMU, Iomega Zip Disk, CD-ROM, and SD cards from my site that all work with Basilisk.  I suggest you use the images you want to modify as your second or later volume under Basilisk II.  In the example below I’ve used my Iomega Zip Disk image as the bootable volume, and I’m modifying my bootable CD-ROM image file before I burn it on to a CD-ROM disk for using on my LCIII.

For Windows I didn’t need to use HFVExplorer, and instead I was able to use the “enable my computer” feature which added a “This PC” icon to my desktop that I could used to access files on my Windows machine to copy in to Basilisk, including copying the OS 7.5.3 upgrade files to install the full version of OS 7.5.3 from the internet archive’s November 2012 snapshot of apple’s FTP site, then upgrading to OS 7.5.5 also from the internet archive’s snapshot.   If you’re using my Iomega Zip Disk image as the bootable volume, I’ve included StuffIt Expander 5.5, which you can use to unwrap the .bin files.

Once you’ve added or removed the files you want for a image, follow the instructions on it’s page for how to copy the updated image on to a floppy disk, floppy-EMU SD or MicoSD card, Iomega Zip Disk, CD-ROM, or SCSI2SD SD card on to the supported device.

  1. Very curious, I’m having problems on my SE. Is this because it’s not a 32bit? Is it because it runs a 68000 Instead of a 68030? I need to use a 32bit rom I understand but then the rom does not match my machines rom. How could I solve this issue?

    • What problems? Will it not boot? Before you try using any of the images I created you’ll need to open the image in Basilisk and then change the memory setting to 24bit and shut down the emulator.
      After you make this change the image will NOT boot in Basilisk, but should boot under your SE.
