On this page I have placed links to a TAR file that contains the include, make, and source code files in order to build software programs for an interested user to discover the fun I have had in creating DOS 4.1, DOS 4.3, and DOS 4.5.  These C programs are capable of processing DSK image files such as reading the file’s catalog, extracting selected files, and recording new files.  I will add more software links as I prepare the files.  I have included links to the ROM images I have created for the Apple //e.  The first ROM image contains the SWEET16 Metaprocessor and the second TAR image contains three ROM images (a CF ROM and a CD/EF ROM pair) that contain both the SWEET16 Metaprocessor and a Garbage Collector designed after the one by Cornelis Bongers.  Just click on the link and the file will download to your computer’s desktop.
