I have just tried the combinations below:

	3/480, 3/4xx memory		Works (of course)
	3/280, 3/2xx memory		Works (of course)

	3/480, 3/2xx memory		Works
	3/280, 3/4xx memory		Works

	3/480, Clearpoint 16M for 3/280	Works, but only if it is
					not the first board in the
					system. If 1st, it fails the
					forced ECC interrupt test.
