Porting NetBSD to MIPS Magnum 3000 would bring a nice desktop
computer.  Most of the hardware components are already in NetBSD
source code tree, and porting effort would be concentrated around the
unique DMA engine support. 

From my volatile memory, it has

- NCR53C94 SCSI 
- "RAMBO" DMA ASIC
- LANCE (?)
- PS/2 style keyboard and mouse (i8042)
- hardclock source is fed by RAMBO ASIC

I think the ROM monitor can boot the system via TFTP (never tried
myself).  Risc/OS had device driver source codes on somewhere in /usr
directory, and they would serve as valuable information resources.  I
remember that once X11 distribution contained X server source code for
Magnum 3000.  It was a good computer as Digital's DECstation 5000
series, I think.
