Malte, Very interesting! We certainly do have a stray capacitance issue here. When I connect my scope to T0 and watch the pulse train going into the CPU the instability on this board stops dead (a bit like removing IC6). I think the probes I am using have a capacitance of 47pF. Hmmm...this is odd...more to follow... Andy [Non-text portions of this message have been removed]
