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
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.
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’’ to be loaded at address 0x1000, with execution at 0x1003. (On
a 6502, this is the opcode for indirect jump to 0x2C6F.)
