ReadMe.txt for http://www.aztecmuseum.ca/AztecCAppleXOrg.zip By Bill Buckels Last Revised August 2008 This zip file contains the complete and original disks from the Manx Aztec C65 Version 3.2b MS-DOS Cross-Development environment for the Apple IIe. The MS-DOS disks are in subdirectories 1-3. The ProDOS disk is in subdirectory 4. The DOS 3.3 disk is in subdirectory 5. However this will not be of much interest unless you are willing to put a fair amount of effort into creating a working environment or you are a collector. The Apple33 and AppleX distributions of this same compiler also available from http://www.aztecmuseum.ca/ are preconfigured for DOS 3.3 or ProDOS targets and come with sample programs. They may suit your purposes better. Other Aztec C Apple II compilers are also available from the website. The Apple side of this compiler distribution (subdirectories 4 and 5) is in the form of diskimages. The previous distribution of this zip file did not include these but in the interim I purchased a Microdrive and a CF card for my Apple //e so I was able to convert the Apple disks to diskimages using the utilities that came on the CF card with the Microdrive and port these back to my PC on the CF card. The DOS 3.3 disk does not provide the DOS 3.3 Aztec C SHELL. The ProDOS disk provides SHELL.SYSTEM. Both disks contain the Aztec C xfer program. When this compiler was produced, the usual way to transfer files between computers (especially different types of computers) was with a serial (NULL modem) cable. The xfer program provided with Aztec C for DOS 3.3 transfers the linker output (the executable) as-is as a DOS 3.3 bloadable binary file with the ubiquituous 4 byte BSave header intact. The ProDOS version of xfer strips this header. In either case the header information is used to record the executable correctly on the target system. Since this linker always tags the 4 byte header on all executables, if Aztec C's xfer program is not used with a serial cable, the ProDOS executables will need to have the header stripped and the file information placed in the ProDOS system by some other means. The AppleX environment has a utility called MAKEPRO that does this. This zip does not, So to recap, the purpose of the Apple disks is to provide an xfer slave on the Apple II to receive file transfers through a serial cable from the xfer master on the IBM-PC. This concludes my synopsis about all this. The Aztec C Museum website has additional documentation for utilities and library functions, and the preconfigured versions can be reviewed for an overview of different working configurations.
