Exploring the Pippin ROM(s), part 6: Back in the ‘rvpr’

(How’s that for a punny subtitle?) It’s been a while. I haven’t lost interest, I’ve just been busy with work and other things.

Exploring the Pippin ROM(s), part 5: Open Firmware

The earliest parts of the Pippin ROM are not much different […]
