5.0 - Creating/extracting disk-images

Eager PC-owners have no doubt turned quickly to this section to learn how to read Apple ][ disks in their 5.25" drives... Well, you can't. Basically, PC drives and Apple drives use different encoding techniques. Check out Section 5.10 in Part 3 of "The Apple II Frequently Asked Questions (FAQ)" guide for more information. But don't panic! Follow this easy two step guide to creating disk- images, and transferring them to the required computer. The following steps apply only to standard DOS, ProDOS and compatible disks (those that can be copied by "Copya"). More detailed instructions are usually given in the archive packages. To transfer ROMs or text files (or indeed any file from an Apple ][), just substitute those files in place of the disk-images in the following examples.

These instructions are primarily intended for creating disk-images of 5.25" diskettes (usually software for 8-bit Apples). With the advent of IIgs emulators, it has become necessary to transfer 800K ProDOS disks. Once again, although these disks are the same media as 720K DOS disks, they are not compatible with PC disk drives. The easiest method to create an 800K disk-image for IIgs emulators on non-Macintosh platforms is to use a Macintosh (which read 800K ProDOS disks as standard) and make a DiskCopy image. This image can then be converted for use with XGS on non-Macintosh platforms (see the 2IMG disk-image format below).
