SUMMARY: Weitec cpu for Sparc2

Hi,
Apparantly my question wasn't too smart - the Weitec achieves its double speed
through clock doubling within the chip only.
The outside speed (cpu board) remains the same and hence the presence of the
Weitec is not detected by the devinfo command.

The way to determine is to run a short program which does integer/fp multiplications and check the performence on a Sparc2 with a Weitec and on one without.
