>>>I haven't yet found the magic flag that write-enables the WCS.

Based on a note by Martin Brenner, I quickly tried this in Manx C
and it sure seems to work

	main()
	{
		* (long *) 0x80 = 0xFC00D0;	/* a RESET */
	#asm
		trap	#0
	#endasm
	}

Compile and run.  The machine'll reboot, but the WCS will be
unprotected and the BootRom will be visible at 0xF80000.

Please don't anyone use this for amything.
