Amiga Hardware DatabaseManufacturer Pangolin Laser Software, USA | Date 1991 | Amiga A2000, A3000, A4000 | Interface Zorro II |
- Laser Display Controller
- provides analogue and digital channels to control a Laser Display system (XYZ-RGB-I) to perform laser shows
- DB-25 connector on the slot bracket
- each analogue output provides bipolar direct current (DC)
- X, Y, Z channels: -5 to +5 volts
- R, G, B channels: 0 to +5 volts
- depth cueing input for 3D applications
- blanking support
- Software
- supported by Pangolin Laser Show Designer LD400 software package
- up to 16.800.000 colors
- up to 4 laser projector operated (requires multiple QM16 cards)
- 3D and 2D mode
- script-based programming to generate laser shows
- support for up to 32 tracks
- support for real-time 3D manipulations
- support for up to 10,000 3D laser frames with up to 2,000 points per frame
- renumbering laser graphics
- real-time laser preview
- Asteroids laser game
- Notes
- although intended as laser controller, the card and software can also be used for other DC control voltage applications
- no protection circuitry on the digital outputs
- DB-25 Connector Pinout
- note 1: all analogue grounds are tied together, as well as all digital grounds
- note 2: all analogue lines (pin 1 - 13) are protected by series resistor (100 Ohm), the digital lines (14 - 25) are directly connected to TTL chip
