Ok, what follows is an ad the a MIPS R4x00 board. Thought you guys may
find it interesting. Hopefully the cost will be a bit less.

> I would like to tell you about the Carrera R4x00, the first
> RISC based PC motherboard. The Carrera R4x00 is a leading edge
> product from Carrera Computers. The Carrera motherboard uses the
> latest in a continuing series of high performance CPU's from MIPs
> Technologies. The CPU is the industry's first 64-bit RISC
> microprocessor and is compatible with popular PC, as well as UNIX,
> application and operating system software. The Carrera R4x00 is
> the choice platform to run Microsoft's Windows NT, as well as USL's
> UNIX. All this power to in a standard AT sized motherboard or
> "baby AT" the VIPER R4000PC-50! The Mips series of processors are
> capable of running at clock speeds from 50 MHz to 200 MHz, with
> all generations of the R4x00PC microprocessors guaranteed pin
> compatible.
> The Carrera R4x00 has several ports embedded for easy
> integration. For example, we have included an industry standard
> SCSI-2 interface to allow access to a wide variety SCSI peripherals
> such as magnetic disk drives, CD-ROMs, tape drives, etc... If you
> prefer to use the Carrera R4x00 as a workstation or a file server,
> an Ethernet port has been designed in to allow network
> connectivity. We have also included common serial/parallel ports,
> keyboard/mouse ports and floppy disk controller to make integration
> a snap!

> At the heart of any powerful "Windowing" computer is the video
> subsystem. The CHEETAH "local bus" video accelerator delivers
> astounding speed at 9,000,000 pixels per second (unaligned bitbit)
> without waiting around. However, our JAGUAR VXL 485 "local bus"
> video accelerator is unlike any other video controller. The JAGUAR
> is a 64-bit design and takes full advantage of the COBRA's 64-bit
> MIPs R4x00 RISC processor and 64-bit data bus. System resources
> are managed effectively and efficiently. The on-board processor
> enable the JAGUAR to preform graphics intensive operations as much
> as ten times faster than typical 32-bit graphics cards. Most local
> bus based systems simply put the controller next to the processor.
> The JAGUAR, is placed near the main memory so that other
> input/output devices also gain access to the processor. This is
> critical for graphics based Windows NT applications. Video
> operations can take place while other input/output processors occur
> simultaneously, without penalty! This allows you to have both an
> operating system software AND hardware, that are truly
> multitasking!
