I've just aquired a Beige G3 DT and cannot get classic to install, it keeps hanging at the yellow desktop with the CD pictures and "CD" writing, if I hit enter then I get a little more optical drive activity and then nothing. I've tried switching out the CPU, GPU, RAM, HD and optical drive but keep getting the same problem, I've tried OS 8.1, 8.6 and 9 to no avail.
