Are things like serial port and SCSI already hooked up? I guess the UART they used is pretty standard (8250?).

But what about Ethernet/SCSI, does the Sun2 support anything that's already supported by MAME (at least chip-wise, I know that the Multibus card itself probably doesn't exist yet)

On a related note, how would I go about running MAME with a machine (like a Sun2 or Sun3) and attach an emulated terminal to its serial port? I searched around a bit but couldn't find a suitable command line for such a configuration.
