[rescue] 670MP windfall in the surplus diving frenzy today.....

[Dave McGuire]

  It's not so much a matter of the operating system, but the windowing
system.  If a bus and a device driver are intelligently designed,
multiple instances of any device can be installed in a system, right?
Well, /dev/cgsix0, /dev/cgsix1, etc.  Now, it's just up to the
windowing system to deal with them, and X has dealt with multiple
heads since the dawn of time.

  Until I switched to an SGI Indigo2 about 1.5yrs ago, my desktop
machine has been a Sun dating back about eleven years.  The first Sbus
machine I ran on my desk was an Opus SS1+ clone back in 1992, which
had two CG3s in it.  Since then I've ALWAYS run dual heads.
