I verified set 18, and this machine verifies it fine, but my second pentium shows the TLE is incorrect. I noticed the mean motion was out, but this machine verified it fine compared to previous sets. I found one of the CPU fans had stopped working and made the error. > >My appologies to all, hardware mistakes was not anticipated.. > > Dave Cottle. > > > -------------- David Cottle IDB Communications.
