W7: Hyperjam

  • vMac.ROM and MacII.ROM Required by Mini vMac to boot.

  • Workstation (Boot).dsk A boot drive that works for both a virtual Macintosh Plus and a Macintosh II. This has HyperCard 2.4.1 already installed, plus some useful system utilities. The popular WindowShade extension has also been installed, so that you can double-click window titlebars to fold and unfold them. System 7.1.

  • Viewer Only (Boot).dsk A minimal boot drive for a virtual Macintosh Plus, with HyperCard Player already installed. Your HyperCard entry should be tested to work on this sytem. This drive/disk image only boots on a Macintosh Plus. System 7.0.1.

  • Blank 800K Floppy.zip A zip file containing a .dsk image of a blank floppy. Extract the .dsk file and give it a better name, then drag and drop it onto Mini vMac to insert the virtual floppy. You should try to get your game jam entry to fit onto one of these. (Macintosh floppy drives at this time were only 800K, not 1.44MB.) The .dsk file is inside a .zip file to make it smaller. It’s mostly zeroes, and compresses down to 1.3K.

  • More Blank Images.zip This is like the Blank 800K Floppy.zip, except it contains a bunch more pre-formatted blank images at various sizes. Use the ‘M’ subdirectory to get images sized in megabytes — for example, 020M.zip contains 020M.dsk, which is a 20 megabyte disk image. The sizes go up to the hundreds of megabytes, though using disk images this large isn’t recommended, because the disks can become corrupted if your Macintosh crashes. You’ll want to be making backups as you work, and it’s harder to back up huge images.

    This is just a renamed blanks-1.0.0.zip from the Gryphel Mini vMac website. Read more about it here: https://www.gryphel.com/c/minivmac/extras/blanks/index.html

Before copying backups of your disk images in your host operating system, make sure to eject your virtual disks by dragging them into the Trash inside of your virtual Mac!
