       srec_wilson - wilson file format

       This  is	 a mystery format, added to support a mysery EPROM loader used
       by Alan Wilson <>

       If you know the true name of this format, please	let me know!  It bears
       a  remarkable similarity	to the Motorola	S-Record format, however I can
       find no reference to a "compressed" Motorola format.

   The Lines
       Each line contains normal ASCII characters, and "high bit on[rq]	 char-
       acters,	but  the ASCII control characters are avoided (the high-bit-on
       con characters are not avoided).	 Normal	 line  termination  characters
       (CRLF or	LF, depending on your system) are used.

       The  presence  of high-bit-on characters	makes this format unattractive
       to send via email, as it	must be	wrapped	as a  binary  attachment,  in-
       creasing	its size.

       In  general,  a	single byte per	byte is	used to	encode values, however
       some values use two bytes, according to the following table:

			Byte Value    Encoding (1 or 2 chars)
		       0x00 .. 0x9F	   0x40	.. 0xDF
		       0xA0 .. 0xAF   0x3A 0x30	.. 0x3A	0x3F
		       0xB0 .. 0xBF   0x3B 0x30	.. 0x3B	0x3F
		       0xC0 .. 0xCF   0x3C 0x30	.. 0x3C	0x3F
		       0xD0 .. 0xDF   0x3D 0x30	.. 0x3D	0x3F
		       oxE0 .. 0xFF	   0xE0	.. 0xFF
       The rest	of this	description, when refering to  "bytes[rq]  means  byte
       values encoded using the	above table.

   The Fields
       Each line consists of 5 fields. These are the type field, length	field,
       address field, data field, and the checksum.

		 |Type | Record	Length | Address | Data	| Checksum |
       Type    The type	field is a 1 character field  that  specifies  whether
	       the record is data (0x43), or termination (0x47).

       Record Length
	       The  record  length  field is a 1 byte field that specifies the
	       number of bytes in the record, excluding	the  type  and	record
	       length fields.

       Address This is a 4-byte	address	that specifies where the data is to be
	       loaded into memory.

       Data    The data	field contains the  executable	code,  memory-loadable
	       data or descriptive information to be transferred.

	       The  checksum is	an 1-byte field	that represents	the least sig-
	       nificant	byte of	the one's complement of	the sum	of the	values
	       represented  by	the  bytes  making up the length, address, and
	       data fields.

   Record Types
       0x43 (#)
	       A record	containing data	and the	4-byte address	at  which  the
	       data is to reside.

       0x47 (')
	       A termination record.  The address field	may contain the	4-byte
	       address of the instruction to which control is  passed.	 There
	       is no data field.

   Size	Multiplier
       In general, binary data will expand in sized by approximately 1.5 times
       when represented	with this format.
