There are six types of Apple ][ disk-images, of which three are Unlike the different types of images above, emulator images can be used on anyĬomputer. (unlike modern software, most Apple ][ applications could not be installed ontoĪ hard-drive and were dependent on the 140K diskette structure to operate).
#UCR FOR MAC EMULATOR SOFTWARE#
Disk-images are used to trick theĮmulator software into thinking that there is an Apple ][ disk-drive attached Although the diskette media itself is the same, the method used to Use disk-images because the original media is not compatible with the modernĭisk drives.
Whereas modernĬomputers use images to transfer physical diskettes electronically, emulators None of these image types are compatible with each other.Įmulators use disk-images for a totally different purpose.
Finally, the Amiga usesĭiskMasher images. WinImage (which is compatible with DiskCopyFast in DOS). Apple distributes its system software in DiskCopy imageįormat (which is compatible with programs such as ShrinkWrap and MountImageĪllowing the image to be accessed like a real disk from the Finder). Use disk-images for storing and transferring disks over electronic networks Physical diskettes may become defective, it makes duplication of master-ĭiskettes easier, disk-images can be stored on hard-disks eliminating the needįor unwieldy numbers of diskettes, etc. Useful because of a number of factors - an "image" of a diskette retains more
#UCR FOR MAC EMULATOR ARCHIVE#
Volume as a software file basically there is little difference between it and aĬompressed archive (eg. The 16-bit IIgs emulatorsĬoming into use now need the latest processors (Pentium or PowerPC chips).Īpple II 5.25" diskettes are not compatible with that 5.25" floppy in theĪ disk-image is a track-by-track copy of a physical diskette made to a fixed Point, it takes the processing power of a 486DX2/66 or 68030 CPU to comfortablyĮmulate a 1MHz 6502 (the CPU of the 8-bit Apple ][). Is really only possible because of the expanding power of computers. Efficient emulation of the Apple on modern machines Emulators can use a large percentage of your physical computer's If the concept of emulation sounds too good to be true - that's probablyīecause it is. Software copy of the ROM (see below) the emulator can use the resources of your Software, and around this is built further emulation of storage devices (usuallyĭisk-drives) and translation so that the virtual-machine can use your physicalĬomputer's keyboard, display screen, RAM and sound features. Instruction-set of the Apple's CPU is duplicated at the core of the emulator as Microprocessor which executes machine-language programs).
