NAME
srec_spectrum - Spectrum file format DESCRIPTION
In this format, bytes are recorded as ASCII code with binary digits represented by 1s and 0s. Each byte is preceded by a decimal address. The file ends with a Control-C character (0x03). Size Multiplier In general, binary data will expand in sized by approximately 14 times when represented with this format (or 15 times on DOS or Windows). EXAMPLE
Here is an example Spectrum file. It contains the data "Hello, World[rq] to be loaded at address 0x0. ^B 0000 01001000 0001 01100101 0002 01101100 0003 01101100 0004 01101111 0005 00101100 0006 00100000 0007 01010111 0008 01101111 0009 01110010 0010 01101100 0011 01100100 0012 00100001 0013 00001010 ^C COPYRIGHT
