Damn Roy, you have your own small Nuclear Reactor to power all that?

I'm using a triplehead for my front view and a dualhead for each side view
- requiring 3 PC's.  Not likely to go the fresnel route on this job, what
we've got so far works ok for us.  Initial setup is here:

I use a dual-head video card (soon to be replaced with a matrox dualhead)
for the J41 sim and that works ok too - I did remove the LCD's from their
caes to reduce the gap between them as much as possible.
