motorola xc rc and rc i just installed a motorola xc rc fpu in an amiga a board mhz with capability to clock the fpu separately previously a mc rc was installed and everything was working perfectly now the systems displays a yellow screen indicating a exception when it check for the presence type of fpu when i reinstall an mc rc the system works fine but with the xc even at mhz it does not work the designer of the board mentioned that putting a pullup resistor on data strobe ohm might help but that didn t change anything does anybody have some suggestions what i could do does this look like a cpu fpu communications problem or is the particular chip dead it is a pull not new moreover the place i bought it from is sending me an xc rc i thought that the rc were labeled mc not xc for not finalized mask design are there any mc rc thanks christian
