This looks like I'm going to have to tack at least 3 types of cables together?
1. Regular 3-core (perhaps 26 to 28 gauge?) for the data (14,15) and ground (13)
2. Coax for video (12) and ground (4/5/6) and shield
3. Thicker core for power (7,8) and ground (4/5/6)
And probably sheath the entire conflagaration in shrink tubing?

Hmmm...is the BCC02 a 15-15 straight cable?
If so then I can whip one up myself instead of paying 20 bucks to a dealer...
Yes, but you really want to use 75 Ohm coax for the video signal. You
also don't need to wire all the pins.
Accordign to my VR201 schematic, the pins used are :
4,5,6 Ground (and shield of the coax)
7,8 +12V (power for the monitor and keyboard)
12 : Composite video
13 : Ground
14 : Data from keyboard
15 : Data to keyboard
Keyboard data is at RS232-ish levels, the power is fused inside the
monitor at 2.5A, but the keyboard is fed on the CPU side of this fuse. So
make sure you use think enough wire!
