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.
