When the 68020 was released Moto got the speeds up to 16Mhz and later 20. By the '040 I think they were running at 50MHz [1] I think I still have the draft list of issues in my files. There was a halt and catch fire style error you had to be careful about (I've forgotten the details - but if you executed it in supervisor mode, the ucode turned on the address drivers in such a manner that they stopped working after that and the chip was ruined). I only did that once ;-) when we were debugging Magix (the OS for Magnolia) --000000000000f157db05ba6fd3d7 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
