Okay, here's what I have for Altec, Altec-GPA + a couple of others that were posted by other people.
The 414z included here is originally from ( I'm pretty sure ) a poster by the name of Vuki ( found on some forum or another > maybe here ? ).
Many values have been interpolated ( by WinISD' auto-calculation feature ).
Place these .wdr files into WinISD's
"driver" folder, which is typically found inside the WinISD folder which is typically auto-created ( I think ) inside the "Documents" folder ( for the current Windows User. )
