NAME

6       srec_formatted_binary - Formatted Binary file format
7

DESCRIPTION

9       This  is  the  PDP-11 paper tape format, described in the DEC-11-GGPC-D
10       PDP-11 "Paper Tape Software Programming Handbook" 1972.
11
12       The file startes with a charcter sequence which  appears  as  an  arrow
13       when punched on 8-hole paper tape.
14              0x08, 0x1C, 0x2A, 0x49, 0x08, 0x00
15
16       Then  follows a byte count, encoded big-endian in the low 4 bits of the
17       next 4 bytes.  The high bits should be zero.
18
19       Then follows a 0xFF byte.
20
21       The data follows, as many bytes as specified in the header.
22
23       The trailer consists of the following bytes:
24              0x00, 0x00,
25       and then a 2-byte checksum (big-endian).
26
27       The alternate header sequence
28              0x08, 0x1C, 0x3E, 0x6B, 0x08, 0x00
29       is followed by an 8-nibble big-endian byte count.
30
31   Size Multiplier
32       In general, binary data will expand in sized very  little  when  repre‐
33       sented with this format.

EXAMPLE

36       Here  is  a  hex  dump  of  a formatted binary file containing the data
37       "Hello, World!".
38              0000: 08 1C 2A 49 08 00 00 00  ..*I....
39              0008: 00 0E FF 48 65 6C 6C 6F  ...Hello
40              0010: 2C 20 57 6F 72 6C 64 21  , World!
41              0018: 0A 00 00 04 73           ....s
