Kit Information - Thayer's Quest was released as a conversion kit only. The Dragon's Lair wiring harness, laserdisc
interface ribbon cable, and score display interface ribbon cable plug directly into the Thayer's Quest main logic board.
Keyboard Emulator - "TQKey" is a program that allows you to use a standard computer keyboard in place of the original Thayer's Quest
keyboard. Check out the Thayer's Quest Keyboard Emulator page.
Player's Name Censorship - The voice synthesis of Thayer's Quest speaks the player's name after it is typed on the keyboard, but the ROM contains a list of
bad words that will be rejected if typed. The Thayer's Quest Uncensored ROM made in 2000 disables the bad word check and
accepts and speaks anything the player types.
Volume Control Wiring Error - Cinematronics made an error in the construction of apparently all Dragon's Lair and Space Ace main wiring harnesses used by
Thayer's Quest. Two pins are reversed in the connector for the volume controls, shorting the right audio channel to ground and creating noise in the system. For
the fix, see the Dragon's Lair / Space Ace Operator Convenience Panel Pinout.
Monitor to TV Swap - If the monitor in your Dragon's Lair, Space Ace, or Thayer's Quest is not up to your liking, you can replace it with a
19" TV. The Monitor to TV Swap page will show you everything you need to know.
LD-V1000 Boot Switch - A simple inexpensive way to build a switch that issues a play command to the
LD-V1000 or LD-V1001. See the
LD-V1000 Boot Switch page.
