| Particularities: | This is just a very primitiv D-Structure.A clone. Just the way the program header is written to the copy at $7C000 is different and the size of the bomb on disk and in memory. In the A version a pointer shows to the original header and copies this original header. In this version a copy of the program header is included at the end of the bomb and will be copied first to the new memory location. |
