srec_os65v - OS65V Loader file format
This format is used by Ohio Scientific OS65V‐compatible loaders. This family of machines includes the OSI C1P, Superboard II, C2, C4, C8, and Challenger III, as well as the UK101, and Elektor Junior. The file startes with a period '.' (0x2E), to ensure address entry mode. then a 4‐digit hex address, followed by a slash '/' (0X2F) to enter the data entry mode. The initial address is always present. There is no need for an additional address record unless there are gaps. Each data byte is represented as 2 hexadecimal characters, and is separated by a carriage return character (0x0D) (advance address). The final return character may be omitted. The data is concluded with a period '.' (0x2E) to re‐enter address mode. If an address to start execution is specified, then the last 5 bytes are nnnnG where nnnn is the 4‐digit execution address, and G is the 'Go' command. Size Multiplier In general, binary data will expand in sized by approximately 3.0 times when represented with this format.
Here is an example ascii‐hex file. It contains the data “Hello, World[rq] to be loaded at address 0x1000, with execution at 0x1003. (On a 6502, this is the opcode for indirect jump to 0x2C6F.) 1000/48^M65^M6C^M6C^M6F^M2C^M20^M57^M6F^M72^M6C^M64^M0A^M.1010G
