cheap RTEMS/PowerPC platform [was: Re: Open Desktop Workstation]

That is not an entirely accurate accounting.  The ODW is a complete  
machine (in a case with PSU, graphics card, memory, hard drive,  
cables, etc.) with all the I/O you could want.  The others are just  

The earlier comparison to the MacMini would be more appropriate.  The  
difference is the ODW has three PCI and one AGP slot and plenty more  
expandability.  You can upgrade the CPU card, graphics card, or  
memory on the ODW, for example.

The ODW is also support multiple operating systems.  We thought RTEMS  
could be one of them.  We are even willing to provide FREE hardware  
to developers that are interested in supporting the port.

We joined the list and made the initial post because we had an  
inquiry from a customer that wanted to have RTEMS running on the  
platform.  Is there any interest?

Hope that clears things up!  :-)
