I always read that a 030 on a 16bit bus is not a good idea.
This might be true, although I did my tests on an A500+ with an ACA500 and my blizz030.
AIBB gave me the exact same results as on my A1200 except some results like Line test because of AGA.
Propably a 50MHz 030 is not fast enough to bottleneck a 16bit bus?
