After a bit more playing I've get the screen modes sorted, the extra resolution are bracketed in the Radeon info file, so I now have workbench running in 1920 X 1200. :-D
The only browser I've installed so far is OWB, the reason for installing it was so I could download installer 43.3 from the aminet. The browser looked good, but defaulted to amigans.net and i can't find a way to change it to A.org :-? When i got into the aminet and found the file i wanted i clicked on it and all the browser did was display a text view of the lha file. I couldn't find a way to save the file so eventually gave up and downloaded it on another computer and passed it to the Sam with a USB stick.
Fat32 USB sticks are recognised without installing any additional software, I've successfully used an 8 gig stick.
As for what I'm going to use this machine for, its a toy like all my Amigas, I cannot in all honesty use an Amiga as a professional platform (I am a programmer but in 4GL database languages). Though I am currently trying to remember C and learn the specifics of coding for the Amiga.
Any advise on os4 development environments and tutorials will be gratefully received.
