I never had much luck using a PS2 keyboard + USB converter on my G4 tower. Any particular brands which seem to work better than others? Any which map to the Apple / Command keys? -- Every keyboard and mouse Apple shipped since Steve came back are crap, esp the puck 'cripple-mice'. My wrists hurt so bad after using one when we first released them that I refused to use them, or any of their descendants. The travel is too short, and the key shafts bind at normal typing speed. Find a macally ikey and a logitech m-bj69 roller mouse. The macally has they key layout of the adb extended kb and has the same key pressure and travel. I've been picking them up fairly cheap in surplus places and on eBay as people dump their iMacs and early G4s. If you're using OSX, the roller mouse does what it's supposed to. What pisses me off is we had a prototype ADB roller mouse that did all the stuff you can do now with the Logitech 15 years ago, including programmable detents on the roller (it actually had a little motor inside..) but couldn't convince people it was useful.
