- Why am I getting them? I am using a 68EC020 with a 68882 coprocessor. I have read the 68882 and
- 68020/EC020 manuals and I don't understand why this is happening. The coprocessor is connected
- straight to the EC020. The 68882 manual states that their could be a problem if you use a
- buffered address strobe while not using buffered lower address lines. I am not buffering any
- lines! Another way for this to occur is through the misuse of the moves instruction. I am not
- using the moves instruction at all. I am at a loss. What other condition can occur in the
- software or hardware to cause this to happen?
