There are four floppies included with PLASMA for users to download. The fourth one is specifically for the Apple III and SOS. You can download them from: PLASMA 1.0 System PLASMA 1.0 Build Tools PLASMA 1.0 Demos PLASMA 1.0 Apple /// SOS Boot
Apple 1The Apple 1 is a very constrained system compared to the ][ and ///. It is required to have the CFFA1 disk adapter installed to provide file storage and a full 32K od RAM. To get the files onto the CF card required the use of CiderPress and they must be placed in one directory. Most PLASMA programs won’t work on the Apple 1 due to limited filesystem support, video/graphics capabilities, and lack of audio output. It does, however, make a good place to start when porting PLASMA to a new platform.
Apple ][To boot directly into PLASMA, you will need to put the system files in the root prefix of the boot device and make sure PLASMA.SYSTEM is the first SYSTEM file in the directory. Otherwise, start PLASMA.SYSTEM from your program launcher of choice. All Apple ][ models with 64K and two floppy drives are supported up to a maxed out IIGS with accelerator and hard drive.
65802/65816 SupportPLASMA can utilize the 16 bit features of the 65802 and 65816 processors to improve performance of the PLASMA VM operation. This is transparent to the programmer/user and doesn’t make any additional memory or capabilities available to PLASMA. Launch
PLASMA16.SYSTEMto use the 16 bit PLASMA VM. If you don’t have the right CPU, it will print a message and restart.
Apple ///The Apple /// gets the environment it always wanted: The ability to navigate the filesystem with a command line interface. The Apple /// always boots from the floppy drive, even if a hard disk is installed. The PLASMA.SOS floppy should be updated with the SOS.DRIVER configured for your machine. Once booted, type
S /HARDISK/PLASMA(or your install directory of choice) to change to, and set, the system directory. This can be automated by creating an
AUTORUNfile on the boot floppy with the above command in it.
