So i recently traded a pc monitor for an eMac with a G4 PPC processor and it worked great for about a week, i restarted and now all i see is a grey screen with a folder flashing the old mac face and a ?. I've looked all over the internet for a solution, there are many but i dont have an apple keyboard, i dont know if that effects anything or not, but when i try some of the key combos to do stuff none of them work.. like if i hold C while booting it doesnt boot from disk.. it trys to boot like normal. If i hit Command + S i dont get the single user mode i get this.. I dont even care about fixing the current version of OS X on it which is 10.4.11 i just want to be able to re-install it! But im having no luck... anyone have any ideas on this PLEASE help me.. PS sorry for the huge picture but atleast you can see what im seeing clearly..
