       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 sepa-
       rated by	a carriage return character (0x0D) (advance address).  The fi-
       nal 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.)
