Haitex can be reached at (803) 881-7518. X-Specs are still available and new products are on the way. Virtual Reality has resurrected interest in the product. >The control line is usually the "fire button" line of the second joystick port. Pin 6 (0xbfe001 in ciaa, see the Amiga Hardware Manual for details), is configured as an output. The bit is toggled during vertical blanking to flip the glasses (VERTB or COPPER interrupt). >The glasses do not work well with long-persistence[sp?] monitors, Flicker >Fixers, or Commodore Display Enhancers. The glasses do not work well with slow-decay phosphor or LC displays. They will not work with the Microway FlickerFixer. They work *great* with the Commodore Display Enhancer [as long as the interlace bit is disabled]. If you write your own copper lists and don't use the "interlace trick" to get 3D, you'll have no problems. Remember my 3D multiplayer dogfight simulator I showed at DevCon Atlanta, running on two A3000s with de-interlacers enabled? >> On second thought,, if you have a set, and are willing to sell them, I >> could negotiate with you regardless of any docs you might have. >> And, if you have no glasses, but have programming docs, I would love >> to work something out with you. You can buy a brand new pair from Haitex. They're giving the Amiga market another shot. John
