(home movie) Dragon's Lair Hack: Spoofing the arcade game's laserdisc player with a PC

In addition to being into playing PC games, I am also into classic laserdisc arcade games (such as Dragon's Lair). See my web site at http://www.daphne-emu.com

Laserdiscs and laserdisc players are becoming more obsolete every day and for a while I have felt that with enough work and research, one could replace a laserdisc player with a PC using the PC's parallel port. This video represents my first step at making this happen.

Details:
Laserdisc player being spoofed: Pioneer LD-V1000
Interface: PC parallel port connected via cable to dragon's lair motherboard
PC specs: AMD Athlon 800 (yes, it's old. I tried an AMD64 2800+ and it failed)
OS: Ubuntu Linux v9.04 (Jaunty) running in console mode
Cable: custom cable soldered by my wife and I
Arcade hardware: original Dragon's Lair machine from 1983

Now that the computer is able to receive the commands, you should get the computer to display the video animation. Then you'd have the equivalent of a hard disk-based machine.

So your monitor is dead at the moment? Would be killer to actually see it running live. Is it actually accessing data you have on your computer taken from the original laser disc, or is the computer simply interpreting the frames the machine is sending for? Cool man!
