CUDA, EGRET, HC6805 Hacking

Recommended Posts

I have found the information into the LPX-040 motherboard developer note : https://web.archive.org/web/20030410054223/http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-PPC_Desktop/LPX-40_Dev_Note.pdf

 

The Cudla Lite is on the clone logic board and on Power Mac 4400. It's like a CUDA classic chip with PS/2 support.

 

On the clone from Motorola, there is PS/2 port, on the Power Mac 4400, there is trace on the logic board only.

Hi crews,

 

I've just started uploading a commented assembly for the Cuda Firmware v2.37, see this Github repository. To my knowledge, that's the latest firmware available but we need to re-check it. In the next days, I'm going to put even more docs on Cuda - so stay tuned!

Thanks for the commented disassembly! Is that the whole thing, or just a part? I didn't see anything in there for how CUDA monitors the power button and asserts or de-asserts /PFW to turn on/off the power supply.
