6 srec_os65v - OS65V Loader file format
7
9 This format is used by Ohio Scientific OS65V‐compatible loaders. This
10 family of machines includes the OSI C1P, Superboard II, C2, C4, C8, and
11 Challenger III, as well as the UK101, and Elektor Junior.

13 The file startes with a period '.' (0x2E), to ensure address entry
14 mode. then a 4‐digit hex address, followed by a slash '/' (0X2F) to
15 enter the data entry mode. The initial address is always present.
16 There is no need for an additional address record unless there are
17 gaps.
18
19 Each data byte is represented as 2 hexadecimal characters, and is sepa‐
20 rated by a carriage return character (0x0D) (advance address). The
21 final return character may be omitted.
22
23 The data is concluded with a period '.' (0x2E) to re‐enter address
24 mode. If an address to start execution is specified, then the last 5
25 bytes are nnnnG where nnnn is the 4‐digit execution address, and G is
26 the 'Go' command.

28 Size Multiplier
29 In general, binary data will expand in sized by approximately 3.0 times
30 when represented with this format.
31
33 Here is an example ascii‐hex file. It contains the data “Hello,
34 World[rq] to be loaded at address 0x1000, with execution at 0x1003.
35 (On a 6502, this is the opcode for indirect jump to 0x2C6F.)
