	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.

> panic: buffers

	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.

> What am I doing wrong?

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