hm.  http://developer.apple.com/technotes/tn/tn1061.html confirms
Option-Command-O-F.  However, the only visible effect of this chord on
our 7300 is to prevent the machine from booting.  Based on this
technote, it appear that the only way I can access OpenFirmware is via a
serial-console connection to the machine, 38400-N-8-1.  Can anyone
confirm?  If so, it's going to have to wait until I can come up with a
cable that can give me a serial connection to the 7300's modem port,
something I don't currently have.
