Under 1.1, you need to run a shim that catches the now-privileged move-to/from-csr (forgot which) instruction trap, and simulates it. > And is there any precaution in messing with the hardware? Other than the normal precautions in mucking with hardware, just one: the 68K has pin 1 facing a different direction than every other chip on the board. I don't recommend this upgrade, unless you just enjoy fooling with the insides of your Amiga. It doesn't buy very much, and can create headaches with external hardware (yanking the '010 from my machine made my system much more reliable). If you want to do it anyway, complete instructions + the software shim can be found on Fish disk #18. Of course, I've also got an '010 for sale :-).
