srec_formatted_binary - Formatted Binary file format
This is the PDP-11 paper tape format, described in the DEC-11-GGPC-D
PDP-11 "Paper Tape Software Programming Handbook" 1972.
The file startes with a charcter sequence which appears as an arrow
when punched on 8-hole paper tape.
0x08, 0x1C, 0x2A, 0x49, 0x08, 0x00
Then follows a byte count, encoded big-endian in the low 4 bits of the
next 4 bytes. The high bits should be zero.
Then follows a 0xFF byte.
The data follows, as many bytes as specified in the header.
The trailer consists of the following bytes:
and then a 2-byte checksum (big-endian).
The alternate header sequence
0x08, 0x1C, 0x3E, 0x6B, 0x08, 0x00
is followed by an 8-nibble big-endian byte count.
In general, binary data will expand in sized very little when
represented with this format.
Here is a hex dump of a formatted binary file containing the data
0000: 08 1C 2A 49 08 00 00 00 ..*I....
0008: 00 0E FF 48 65 6C 6C 6F ...Hello
0010: 2C 20 57 6F 72 6C 64 21 , World!
0018: 0A 00 00 04 73 ....s
