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
between data bytes are ignored.
Using the comma (,) line continuation character resumes from the next address in
!Maaaa dd ... dd,
dd ... dd
Using the semicolon (;) line continuation character takes an address on the next
!Maaaa dd ... dd;
aaaa dd ... dd
It is also possible to have the semicolon immediately after the command.
!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.
