Name: Generic Vector Display (compatible)
ID: 0x3c704111
Version: 1

A prototype integrated three-dimensional vector display system with electron gun array, highly-fidelity electromagnet drivers and controller electronics.

Display area: 1m^3.  Resolution: 1/65536m in each axis (15 microns).

Interrupts do different things depending on contents of the A register:

 A | BEHAVIOR
---+----------------------------------------------------------------------------
 0 | Set mode: off
 1 | Set mode: test cube pattern
 2 | Set mode: user input
 3 | Turn on flare point, set target position to (X,Y,Z)
 4 | Turn off flare point, set target position to (X,Y,Z)
 5 | Set noise level to B (0 = 0%, 0xffff = 100%)
 6 | Set rotation position to B (0xffff = 360 degrees)
 7 | Set B to rotation position
 8 | Set autorotation speed to B degrees/second (B is signed)

Coordinates specified are signed integers.
