GSoC 2015: Enabling Mac OS 9 support in QEMU
by Cormac O'Brien 13 May '15

13 May '15

Hi all, My name is Cormac O'Brien and I'm one of QEMU's student developers for Google Summer of Code 2015. My project goal is to have Mac OS 9 running on both the g3beige and mac99 machines by the end of the summer (it currently doesn't boot on either). I'll be working with Alexander Graf and Mark Cave-Ayland to get things working. You can follow the project at http://c-obrien.org/qemu-os9/ -- updates will be coming more frequently now that I'm officially on the project. If you have any questions, suggestions or information that you think would help, please don't hesitate to email me. I'm excited to be working with the QEMU community over the summer, and I'm looking to continue on with the project after GSoC. ~Cormac O'Brien
