- Dimension's stuff supports SVGA. They recommend local bus. The SPEA
- board is an option.

- If you're after quick 'n' dirty desktop VR with a bunch of basic
- end-user construction tools then you might find yourself considering
- Dimension kit. If you're after a more flexible, developer-level system
- with better support for intricacies of 3DG and structuring interactive
- 3D apps you'd probably consider Sense8's WTK. If you want X% of both
- systems for 0% of the price, you'll find it worthwhile to check out
- REND386. I'm not convinced of the wiseness of your comments on their
- relative performance, Diego.
