Following is a log of what to type at the "_at_" prompt:

sim> b rl0
_at_r <---- Note: Once you make a typing mistake, you must restart.
_at_boot e.g. It will ONLY return another @ for anything you type.
_at_ <---- ^E typed to break to the simulator monitor
Simulation stopped, PC: 157530 (BGE 157526)
sim> b rl0
_at_boot <---- Start the boot program from the disk
Boot
: rl(0,0)unixnix <--- You may make corrections, etc, in this program
unix not found
: rl(0,0)unix
mem = 205376
...

Hope that helps :)
