srec_cosmac - RCA Cosmac Elf file format
This file takes the form of one or more RCA Cosmac Elf monitor
commands, also known as the IDIOT/4 monitor. Only the change memory
command (!M) is allowed.
The general form of the !M command takes the form
!Maaaa dd ... dd
The !M command writes data byte bytes (represented by character pairs
dd) into successive memory locations, started at address aaaa. Spaces
between data bytes are ignored.
Using the comma (,) line continuation character resumes from the next
address in sequence.
!Maaaa dd ... dd, dd ... dd
Using the semicolon (;) line continuation character takes an address on
the next line
!Maaaa dd ... dd; aaaa dd ... dd
It is also possible to have the semicolon immediately after the
!M; aaaa dd ... dd
All of these forms may be used in combination.
In general, binary data will expand in size by approximately 2.0 times
when represented with this format.
Here is an example Cosmac file. It contains the data “Hello, World[rq]
to be loaded at address 0x1000.
