Yep, that now works, thanks.

On the Pro Mini with a test text screen of circa 64 characters the software SPI takes 1954mS to write the screen and in hardware SPI mode it takes 387mS.

Excellent - thanks again for your help.

I could eke out a bit more speed by directly writing to the ports for the control pins but that will break compatibility just for that extra bit of speed. As it stands it should work on every Arduino board with an SPI and enough GPIO pins.
