2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues.
2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)
Binary file
A CoCo binary file can contain sheer data or one or more executable machine language programs. They can be loaded into memory using the LOADM or CLOADM commands. Included in the format is the load address of the binary as well as an execution address. They may contain multiple loadable sections, each of which has its own load address. Each section starts with a preamble that is five bytes long. The first byte is zero. The next two bytes specify the number of bytes to load and the last two bytes specify the address to load the bytes at. Then, a string of bytes follows containing the program and/or any data. After this there may be another preamble followed by more data/code or a postamble. The postamble is also five bytes in length. The first byte of the postamble is $FF, the next two are zero, and the last two form the execution address for the binary section.
| contents | length | meaning |

| 16 bit | length | |
| 16 bit | start address | |
| variable | data/code | |
| $FF 00 00 | 24 bit | marker |
| 16 bit | exec address |
