Tried a CS060MK2 in a A3000 with 1.4ROM's and all it produce is a black screen and that's that. First thought INT2 so had that done, still nothing. Same happened when a 3640 was installed. So you actually need at least Kickstart 2.0 to be able to start an A3000 with 040+. Neither Blizkick or the internal "softkick" in the A3000 will work as the machine doesn't get as far as to load anything.
