Very good. Its not impossible that even the original emulation or tests have bugs, so that has to be ruled out first.

With the FPSP for 040? No, that is organized differently. Instead of the callouts, it is a library that is expected to be linked with certain user-supplied functions. Also i haven't found any binary, precompiled versions so far, so it would be difficult to rule out any assembler problems. And most of the tests are 060 specific anyway, the integer tests for example won't trigger an exception on 040.


What would be interesting to know though, whether the FPSP060 package can also be used for 040. So far i think that should be possible, but maybe i missed some tricks, especially when the fsave frame is manipulated.
