	Try "set cpu 22b" instead.  Using 18b tells the simulator you have
	a 248kb (and 8kb for the I/O page) machine and that is not enough 
	for 2.11 to load and allocate all the resources it needs.

	Yep -that panic message says the kernel could not allocate any
	memory for the buffer cache.  I am almost certain that means
	there is not enough free memory left out of 248kb.

	Try telling the emulator to use "22bit" mode.  If that still
	fails let us know.  Then it will be time for "Plan B" ;)
