yeah, had the AmiJoe ever really existed in public beyond the proto stage at MetaBOX. That was really a tragic one, I really wanted one of those cards, but even Dave Haynie couldn't save that one.
as to the 4GB thing, aren't you referring to disk partition size, not RAM? or is 'memory addressing' and the 4GB limit on OS 3.1 partition sizes the same thing?
