maddoxnero Posted May 28, 2008 Share Posted May 28, 2008 Hello, I currently use an intel mac. I have a g4 logic board but, no power supply to use it. So, I thought I'd ask. What was the programmers button for? Did it load a different OS to program with? Document links if possible are welcomed.

spacklewoof Posted May 29, 2008 Share Posted May 29, 2008 i think one was a reset button and the other brought up a console window. Mind you, I'm pulling this back from 1990. Back when mac's ran 68xxx chips and PPC was new. -w00f Link to comment https://www.insanelymac.com/forum/topic/107312-programmers-button/#findComment-762142 Share on other sites More sharing options...
QckSlvrGuyInKC Posted May 29, 2008 Share Posted May 29, 2008 Programmer's button actually served two purposes - it brought up a console window for debugging purposes, and it also was used on the new world Macs (B&W PMG3, PMG4, and iMac G3/G4 from what I can remember) for updating firmware.
