    PowerBook 520c Screen Issues

It briefly shows colors before going all black so I’m wondering if it’s something with the inverter board or the cables. Any help is appreciated. Emmy

    GCC on A/UX?

    Figure i'd ask here since I have A/UX on a quadra, Has anyone gotten gcc (GNU C compiler) fully installed and setup on A/UX? If so, please tell me how you did it. I'd like to add some other newer GNU stuff like sudo or bash but they require gcc to compile them. It's been quite some fun trying...
