None of the above should be needed to test this. A plain A3000/030 with Zorro II expansion card with Zorro II memory should suffice. > About ZII memory… I still might have a ZII card with some memory on it, but > memory with <5 MB/s bandwidth? Come on...!! ;) The point is that the kernel (probably) crashes if there is Zorro II memory present. There is no plan to make everything run from that slow memory ;-) Hmm, perhaps I can just fake Zorro II memory in a memfile, and test it on my A4000?
