Long time ago I had a CRT eMac connected by miniVGA?<>RCA out to a TV. and I had a irDA (I think from a laptop) connected to USB.
I think the eMac was a G3 800Mhz which was OS limited, but you could clone the drive from a G5 I had access to at the time. Also somehow I installed Front Row app from a newer OS.
Was a pretty sweet setup for back in the day.
