It has been tested that OS 6.0.8 can format the SCSI disk as well as doing a full installation from floppy disk to the harddisk. Unlike the floppy the SCSI disk is writable and data can be written to the disk from within the core. The format of the disk image is the same as being used by the SCSI2SD project which is documented here. Copy the boot.vhd to MacPlus folder and it will be automatically mounted at start.

The harddisk image to be used can be selected from the 'Mount *.vhd' entry in the on-screen-display. This is currently sufficient to read and write the disk, to boot from it and to format it using the setup tools that come with MacOS 6.0.8. The core implements only a subset of the SCSI commands. This MacPlus core implements the SCSI interface of the Macintosh Plus together with a 20MB harddisk. A shell script has been provided for convenience at releases/bin2dsk.sh. Under Linux these can be converted into the desired dsk format using Linux stuffit, unar and dc2dsk in that order. Official system disk images are available from apple at here. Thus it's recommended to wait for the desktop to appear until a second floppy can be inserted.īefore loading a different disk image it's recommended to eject the previously inserted disk image from within MacOS. The first entry in the OSD refers to the internal floppy disk, the second one to the external floppy disk.Ĭurrently floppy disk images cannot be loaded while the Mac accesses a floppy disk. Single sided 400k disk images have to be exactly 409600 bytes in size.īoth the internal as well as the external floppy disk are supported. Double sided 800k disk images have to be exactly 819200 bytes in size. Floppy disk image formatįloppy disk images need to be in raw disk format. MacPlus will then boot into the MacOS desktop.

The upload of the disk image will take a few seconds. Open the on screen display using the F12 key and select theĪ disk image. Disk605.dsk) to MacPlus folderĪfter a few seconds the floppy disk icon shouldĪppear. Copy the *.rbf onto the root of SD card.I've tried to optimize the code with converting to synchronous style and fixing some glitches and instabilities. This is a port of the Plus Too core from MiST which is the port of the Plus Too project.
