	Try swapping around a few addr an/or data lines. It won't
	prevent someone from copying it, but will make it harder
	to use. 

	A security fuse cannot protect a ROM - after all, the CPU must
	get the data somehow. I can sell you a large quantity of write-only
	memories - under 10mW, 1Megx8, 100nsec for a good price.... :)
