Anyway, I also have TiEmu running on this box; I compiled that a few months ago. So what this all means is that I can continue writing Punix!
I was also pleasantly surprised to see that TiEmu can run at full speed at about 40% CPU usage on my PowerMac:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
13205 christop 20 0 60892 31m 19m R 39.7 3.1 3:52.70 tiemu
On my 300 MHz Pentium II laptop, TiEmu runs at about one-fifth of full speed. Go PowerPC!
