Thanks, the question was whether it would be useful to implement the
	ioports = '3f8-3ff'
	irq = 4
syntax as well as the
	ioports = ['3f8-3ff']
	irq = [4]
but it looks like you are actually using the array version anyway?

I think I'd rather avoid implementing both options unless there is a
strong reason to do so.

Ian.
