Thanks to all that helped me, Bob, Dave, Dan, and Matthew.  I have it 
now set up so that I'm serial consoled in to my IIci.

This is for the archives, to serial console only into a 68k Mac (run 
it headless) requires three mods: make sure you choose the serial 
console options in the Booter then turn on the console in the 
/etc/ttys, in my case tty00, and turn off the ttyE0 console in ttys. 
And not to miss the obvious, hook up a serial cable into the modem or 
printer port and run a terminal program to monitor that line and, 
voila!, you have a headless beast.
