Startup script finishes by printing a little message that Control-Shift-L is needed to log on from the console. I then press C/S/L and enter username and password. Notice the silly little debug message indicating the size of the largest kernel stack usage so far is 2260 bytes.
After logging on, I enter a show system -devices command, which starts out by printing some system memory stats. Notice the different characters of the command entry echoing in different colours, indicating the interrupt and corresponding echo being processed by various CPU's.
