We should get all the members to register Mac OS 9 on the same day, then call tech support and ask when 9.2.3 is being released

Depends on the model lokki. Some of them have hardware-specific issues that a couple of ThinkClassic guys are slowly working through. One of the biggest issues is that mobile video card drivers were never written to run in os9 for late-G4 laptops.

Video is the issue for the 12" 1.5GHz. It's running a 64 MB GeForce FX Go5200 for a video card, which was never used in an OS9-compatible laptop. So unless someone can patchwork together video extensions from bits and pieces of OSX drivers, it would have to run video off of the CPU and it would be essentially worthless.

Kinda has a lot going against it, beside the Bluetooth 2.0, AirPort Extreme and USB 2 being a total no-go, I doubt the "GeForce FX Go5200" would emulate the "NVIDIA GeForce4 440" and load the driver for acceleration, but please give it a try.

Also, as we have discussed the PowerPC 7447A processor is possible under OS9, but needs OF modifications, so you may need a few OF commands before you can even try our "Unsupported OS 9 Install"

I am guessing overall, it will have many "deal breaker" items, like No USB, No WiFI, No Ethernet, and Low res graphics :(
