- Actually AJ Redmer discussed the system in c.s.a.hardware back in August. He
- certainly did not hide the fact that the Amiga is _critical_ to the
- performance and capability of Virtuality. Part of his (multiple) responses

- Actually the Virtuality hardware is not quite configured that way. We do use
- Amiga 3000 motherboards. There is one each per unit. We use it as the floppy
- controller. The graphics are generated on a pair of custom cards that
- feature the TMS34020 graphics processor. Each board has a 34020 accompanied
- by a floating point processor and 6 meg of dram. All the graphics are stored
- on the cards. We use one card each for each eye. The audio comes from a
- combination of the Amiga sound chips, CD ROM drive and the players voices.
- There are microphones in the headsets. The machines are networked with
- custom EtherNet RS422 Thick-Mode cards. The hardware with all the boards is
- actually VERY expensive and accounts for most of the cost. The stand-up
- system sells for about $60,000 and the sit down is about $50,000.

- The main reason that the graphics seem to be primitive is that detail has
- been sacrificed for speed. There is great necessity for the (two!) screens
- per player to be updated according to head movement as fast as possible.
- [Potential descriptions of nausea due to virtual "lag" time deleted.]

- BTW, I got a chance to look in the base of one of the Dactyl Nightmare units
- (it sure can't be called a console), and packed away in a steel cage is an
- A2000-like case with (apparently) an A3000 motherboard. The only visible
- part of the front had a power and reset button and access to the CD-ROM and
- floppy drives. Very nicely done.
