This is probably what caused the issue. The "sandmath" rom is an older version, for all that matter you can delete it as it has old revisions of the programs, superceded by the "SandMath_8k" , or the "SandMath_12k" - which is a superset of the 8k version, plus another 4k containing the "Algebra" section (i.e. matrix, vectors and polynomial programs).
In summary:
Sandmath - old and superceded.
SandMath_8k = Main Module, does not need Advantage
SandMath_12k = SandMath_8k + Algebra ROM.
Only the programs in the Algebra part require the Advantage ROM.
Hope this clarifies.
