one of the most progressive inventions by our genius Ken Thompson was, that *NIX regards files as simple byte streams, whereas fixed sized records are a anachronistic relic of mainframes. *NIX "records" always are delimited by a special character.

NAME
srec_fairchild - Fairchild Fairbug file format
DESCRIPTION
The Fairchild Fairbug format has 8-byte records. A file begins with an address record and ends with an end-of-file record.
There are three record types in this file format.
Address records are of the form
+--+------+
|S | nnnn |
indicating the address for the following data records. +--+------+
Data records are of the form
+--+------------------+---+
|X | ffffffffffffffff | c |
Each data record begins with an X and always contains+8-data-bytes.--The-ff+characters are hexadecimal byte values (8 bytes). Each data
byte is represented by 2 hexadecimal characters. The c character is a hex digit being the the nibble-sum of the data bytes. A 1-digit
hexadecimal checksum follows the data in each data record. The checksum represents, in hexadecimal notation, the sum of the binary equiva-
lents of the 16 digits in the record; the half carry from the fourth bit is ignored. The programmer ignores any character (except for
address characters and the asterisk character, which terminates the data transfer) between a checksum and the start character of the next
data record. This space can be used for comments.
The end-of-file record has the form
+--+
|* |
The last record consists of an asterisk only, which indicates the end-of file.
Size Multiplier
In general, binary data will expand in sized by approximately 2.4 times when represented with this format.
EXAMPLE
Here is an example Fairchild Fairbug file. It contains the data "Hello, World[rq] to be loaded at address 0x1000. Notice how the last
record is padded with 0xFF bytes.
