Is it possible to get at least one serial port (emulated COM port over 
USB) onto Atlas the motherboard? There are a number of peripherals that 
need to be hooked up to the system, GPS engine, TNC's, just to name a 
few. Can the FPGA handle that, Leon? There are a lot of applications 
that need to see a COM port to work, so the FPGA needs to emulate that 
transparently.

The 128 pin FX2 has two serial ports, that would be easy. One could also 
run one 8 bit bus (or more) off the FX2 onto the Atlas, would be handy 
to have a small data buss bypassing the FPGA.

Eric, the newer V2.0 ATX PSU's come with a 24 pin Molex connector. But 
you can plug the 20 pin Molex from older pre V2.0 ATX PSU's into that as 
well.
