Power Mac 5200/Performa 5200 support?

[eisnerguy1]

I was wondering if there's been any work on adding Power Mac 5200/Performa 5200 support? I did find this project listing from August 2024. My family's first Mac was a Performa 5215CD and it would be amazing to digitally recreate the experience.

Thanks!

Some commentary from maximumspatium on this:

Strictly speaking, those machines are Quadras 630 where a 68K CPU has been replaced with a PowerPC one. Due to the fact that that HW can't speak the 60x bus protocol, a translation ASIC called Capella has been added. It sits between the CPU and the system bus. The big difference is therefore the CPU replacement and the fact that we're dealing with 68K HW here. No register references for the vital ASICs (F108, PrimeTime II and Valkyrie) are publicly available so chances to support those machines are low.

Valkyrie does have some code included with Marathon II, but the other two have no known documentation or code.
