 		 #138602 - Now there IS nonvolatile storage
Responding to: ???'s previous message
Lattice, Altera, and Xilinx all have relatively new technology and ACTEL has had nonvolatile FPGA's for quite some time, that operate without an external boot PROM. You could build in a counter for number of power-cycles, and make it relatively large. If he runs out of reboots, he can beg for more, but doesn have to come back and explain what his situation is. A 6-bit PC would be a mite short for evaluating whether it actually runs satisfactorily within a fairly complex task that interacts with hardware you've designed yourself.
