-- This image has the console version of RIM at 7756, 
-- the BIN loader at 7777, and Focal 1969 at 0200.  
-- (This would be a fairly typical core image for a 
-- system with just a console and 4K of memory.)
-- If the console input were working, it would allow
-- use of Focal and loading of diagnostics or other
-- software from the console.
