Memory Image format E/A Module
The memory dump format is a headered ROM dump format from the memory chips from the CPU address space, used for loading program files using Editor / Assembler cartridge option 5.
The contents of these files are taken from the CPU address space, so there must be meta-data about the origin of the data. In fact, these files are commonly 8198 bytes long, that is, 6 bytes for header information plus the common size of a ROM (8K).

Address
