Now this is getting interesting. I can get into openfirmware by
sending a break signal over a serial connection. There is still one
problem before I think about storing the keyboard. 

How can I start the machine? 

With the PowerMacintosh 6500/300 I don't have a power switch, except
for the power key on the keyboard. I am wondering if there is someway
I can turn the machine back on, if I should happen to turn it off or
lose power. It seems that there must be some way, or why would the
machine be designed to work through the serial port if the only way to
turn it on is with the keyboard.
