Thanks for the tip. I wasn't aware of the different screen sizes. I wrote the
scroll code over a couple of hours after getting the left and right border
overscan working (finally!). I put in the top border bit to get over the loss
of screen.  I always assumed STs were all the same. All I know is that my code
works on my ST so I'm happy :-) But no matter, I'm sure any hackers who've
seen my code and understand the principles can sort out the technicalities.
