OS 9 on an eMac (1.42 GHz)
« on: October 21, 2023, 02:08:46 PM »

I've got a 1.42 GHz eMac that a long while ago I put OS 9 on.
As expected, the biggest roadblock is the onboard Radeon 9600 (internal name Apollo).
I'm wondering if there's any progress on an NDRV for that graphics chip.
Thanks.

[...] OS 9 [...] Radeon 9600 [...] I'm wondering if there's any progress on an NDRV for that graphics chip.

None that I know of. But you can always be the chosen brave one who does a combination of:
- Reverse engineering the 9200 drivers for OS 9;
- Reverse engineering the 9200 drivers for OS X;
- Reverse engineering the 9600 drivers for OS X;
- See what changed between 9200 and 9600 drivers for OS X, and try to hack the existing 9200 drivers for OS 9 or create one from scratch based on the findings.
And/Or:
- Check out GNU/Linux source code for 9200 and 9600 drivers and do the same as above;
- Check out BSD (FreeBSD, OpenBSD, NetBSD etc.) source code for 9200 and 9600 drivers and do the same as above;
- Check out MorphOS source code for them (assuming they released that part of the source code).

Not sure if ATI / AMD docs that could help, old and/or new, exist.

If doing it, getting advice from @darthnvader might be a good idea.
