       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.

   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.)
