srec_formatted_binary(5) File Formats Manual srec_formatted_binary(5) NAME srec_formatted_binary - Formatted Binary file format DESCRIPTION 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 starts with a character 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: 0x00, 0x00, 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. Size Multiplier In general, binary data will expand in sized very little when represented with this format. EXAMPLE Here is a hex dump of a formatted binary file containing the data "Hello, World!". 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 COPYRIGHT srec_cat version 1.64 Copyright (C) 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 Peter Miller The srec_cat program comes with ABSOLUTELY NO WARRANTY; for details use the 'srec_cat -VERSion License' command.
