These are the original DS/1000 ROMs (date code 2003) without the 7974 
loader extension.  That was added in 1985 (date code 2540) with the 
80070-72 set.  The 12992-80011 ROM loads the extension from the DS/1000 
ROMs into memory for execution.

Contact me off-list if you still need copies of these ROM files.
