This is a port of the [Plus Too core](https://github.com/mist-devel/mist-binaries/tree/master/cores/plus_too) from MiST which is the port of the [Plus Too project](http://www.bigmessowires.com/plus-too/).
|
||||
|
||||
I've tried to optimize the code with converting to synchronous style and fixing some glitches and instabilities.

|
||||
|
||||
## Usage
|
||||
|
||||
* Copy the [*.rbf](https://github.com/MiSTer-devel/MacPlus_MiSTer/tree/master/releases) onto the root of SD card
|
||||
* Copy the [boot.rom](https://github.com/MiSTer-devel/MacPlus_MiSTer/tree/master/releases) to MacPlus folder
|
||||
* Copy [boot0.rom & boot1.rom](https://github.com/MiSTer-devel/MacPlus_MiSTer/tree/master/releases) (Plus and SE ROM files) to MacPlus folder
|
||||
* Copy disk images in dsk format (e.g. Disk605.dsk) to MacPlus folder
|
||||
|
||||
After a few seconds the floppy disk icon should
|
||||
appear. Open the on screen display using the F12 key and select the
|
||||
a disk image. The upload of the disk image will take a few seconds. MacPlus will then boot into the MacOS desktop.
|
||||
After a few seconds, the floppy disk icon should appear. Open the on-screen display using the F12 key and select the a disk image. The upload of the disk image will take a few seconds. If a bootable system is found on disk, a smiling Mac icon will appear. MacPlus will then begin booting into the desktop.
|
||||
|
||||
## Floppy disk image format
|
||||
## Floppy disk support
|
||||
|
||||
Floppy disk images need to be in raw disk format. Double sided 800k disk images have to be exactly 819200 bytes in size. Single sided 400k disk images have to be exactly 409600 bytes in size.
|
||||
Internal and external floppy disk drives are both supported. The first and second entries in the OSD correspond to the internal and external floppy disk drives, respectively.
|
||||
|
||||
Both the internal as well as the external floppy disk are supported. The first entry in the OSD refers to the internal floppy disk, the second one to the external floppy disk.
|
||||
Floppy disk images need to be in raw disk format (a.k.a. DiskDup format) with a .dsk extension. Single-sided 400k disk images must be exactly 409,600 bytes in size. Double-sided 800k disk images must be exactly 819,200 bytes in size. Disk Copy 4.2 files are not currently supported. They are largely the same as raw disk format, but include an additional 84-byte header. A tool to convert DC42 format to dsk is available [here](https://www.bigmessowires.com/2013/12/16/macintosh-diskcopy-4-2-floppy-image-converter/).
|
||||
|
||||
Currently floppy disk images cannot be loaded while the Mac accesses a floppy disk. Thus it's recommended to wait for the desktop to appear until a second floppy can be inserted.
|
||||
Currently, floppy disk images are not writable within the core.
|
||||
|
||||
Before loading a different disk image it's recommended to eject the previously inserted disk image from within MacOS.

|
||||
|
||||
Official system disk images are available from apple at [here](https://web.archive.org/web/20141025043714/http://www.info.apple.com/support/oldersoftwarelist.html). Under Linux these can be converted into the desired dsk format using [Linux stuffit](http://web.archive.org/web/20060205025441/http://www.stuffit.com/downloads/files/stuffit520.611linux-i386.tar.gz), unar and [dc2dsk](http://www.bigmessowires.com/dc2dsk.c) in that order. A shell script has been provided for convenience at [releases/bin2dsk.sh](releases/bin2dsk.sh).
|
||||
Note that the floppy disk drive will not be read when the CPU speed is set to 16 MHz.

## Hard disk support
|
||||
|
||||
This MacPlus core implements the SCSI interface of the Macintosh Plus together with a 20MB harddisk. The core implements only a subset of the SCSI commands. 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 MacPlus core supports SCSI hard drive images up to 2GB (HFS) in size, with a .vhd extension. The core currently implements only a subset of the SCSI commands. This is sufficient to read and write the disk, to boot from it, and to format it using the setup tools that come with System 6.0.8.
|
||||
|
||||
The harddisk image to be used can be selected from the "Mount *.vhd" entry in the on-screen-display. Copy the boot.vhd to MacPlus folder and it will be automatically mounted at start. The format of the disk image is the same as being used by the SCSI2SD project which is documented [here](http://www.codesrc.com/mediawiki/index.php?title=HFSFromScratch).

|
||||
|
||||
Unlike the floppy the SCSI disk is writable and data can be written to the disk from within the core.

|
||||
|
||||
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. But keep in mind that this is an early work in progress and expect data loss when working with HDD images.

It has been tested that System 6.0.8 can format the SCSI disk, as well as doing a full installation from floppy disk to the harddisk. However, keep in mind the core is an early work in progress and expect data loss when working with HDD images.
|
||||
|
||||
A matching harddisk image file can be found [here](https://github.com/MiSTer-devel/MacPlus_MiSTer/tree/master/releases). This is a 20MB harddisk image with correct partitioning information and a basic SCSI driver installed. The data partition itself is empty and unformatted. After booting the Mac will thus ask whether the disk is to be initialized. Saying yes and giving the disk a name will result im a usable file system. You don't need to use the Setup tool to format this disk as it is already formatted. But you can format it if you want to. This is only been tested with OS 6.0.8.

|
||||
|
||||
A tool to create harddisk images (with working SCSI driver and partition table) is available [here](https://diskjockey.onegeekarmy.eu/).
|
||||
|
||||
## CPU Speed
|
||||
|
||||
The CPU speed can be adjusted from "normal" which is roughly Mac Plus speed to "Fast" which is about 2.5 times faster. Original core couldn't boot from SCSI in turbo mode. This port has workaround to let it boot even with turbo mode.
|
||||
The CPU speed can be adjusted to 8 MHz (original speed) or 16 MHz. This port implements a workaround to allow booting from SCSI when using the 16 MHz configuration.
|
||||
|
||||
## Memory
|
||||
|
||||
512KB, 1MB and 4MB memory configs are available. Cold boot with 4MB RAM selected takes some time before it start to boot from FDD/SCSI, so be patient. Warm boot won't take long time.
|
||||
1MB and 4MB memory configurations are available. Cold boot with 4MB RAM selected takes some time before it starts to boot from FDD/SCSI, so be patient. Warm boot won't take as long.
|
||||
|
||||
## Keyboard
|
||||
The Alt key is mapped to the Mac's command key, and the Windows key is mapped to the Mac's option key. Core emulates keyboard with keypad.
|
||||
|
||||
The Alt key is mapped to the Mac's Command (⌘) key, and the Windows key is mapped to the Mac's Option (⌥) key. Core emulates keyboard with numeric keypad.
