At last after a day trying to get my old GLCD working on my new Uno I find this thread and the link to a working library!!
Am working through the "Arduino Cookbook" which I find very useful but the libraries are not included in the downloads.
Much Googling and trying Version 2 and version 3 beta of GLCD libs ( they wouldn't compile ) but just downloaded from this thread and bingo!!
After about 6 years my GLCD spoke to me!!
Many thanks
Will
