A bit of a further update.
The scope is able to be cajoled into running the RA motor in polar mode without doing a proper star alignment. Assuming I do a decent polar alignment of the mount itself so it tracks nicely, I am able to start the alignment in "EQ South" mode for a one star alignment, let it suggest an alignment star then press enter and then align as if I have actually pointed to the assigned star and off it goes with the RA (Previously azimuth) drive running. Obviously goto's are no good as it is not pointed where it thinks it is but it allows me to get around my bugbear of having to wait for it to slew if I am not feeling lazy and letting it do the goto for me.
If I wan't goto to work I can always actually point it at the suggested star and align the electronics properly. It is just a pity the encoders are on the motors and not the axes as then it would be able to retain an alignment either in Alt/Az or polar mode with the clutches relased.
