Does the version 2 SysEnvirons return the correct value for a 68882 coprocessor on the IIx? Previous versions only checked for the 68881, and returned FALSE in hasFPU if any other FPU (like the 68882) was installed. I understand Excel had some problems with the IIx for this reason... Is there now, or will there be, an integer returned to determine the *type* of coprocessor? (not just the existence of *a* coprocessor)...
