1010*  TODO:
1111*  * Figure out why it says the first speech line twice; it shouldn't?
1212*    It sometimes does this on Voice Sensory Chess Challenger real hardware.
13*    It can also be heard on Advanced Talking Chess Challenger real hardware, cold boot.
13*    It can also be heard on Advanced Talking Chess Challenger real hardware, but not the whole line:
14*    "I I am Fidelity's chess challenger", instead.
1415*  * Get rom locations from pcb (done for UVC, VCC is probably similar)
1516*  * correctly hook up 7002/VBRC and 7014/bridgec3 speech so that the z80 is halted while words are being spoken
