BMON video switcher

Hi, Can anyone tell me how to connect an eyetech BMON video switcher to a towered A1200. I bought this item on ebay and have not got any idea how to use. Help appreciated.

This thing is designed to be used with a BVision graphics card and a DCE/Eyetech internal Scandoubler.
Basically, you hook up the ribbon cables from the BVision (right) and the Scandoubler (left) to the two 10-pin inputs, and connect the small 2-wire lead from the switch panel to its connector, note the orientation.

The pins on the back of the BMon looks somewhat like this:

●●●●●  ●●  ●●●●●
●●●●●  ¤●  ●●●●●

Leftmost 10 pins: AGA/scandoubler input.

2 left pins in the 4-pin cluster: Switch
The ¤ is where the red wire from the switch goes.

2 right pins in the 4-pin cluster: Optional KMon keyboard switch input, from EyeTechs EZkey interface.

Rightmost 10 pins: Bvision/Cvision input

The 'notches'/keys on the ribbon cable IDC connectors should point downwards.

Nice, now I know how to connect my BMON, except for one thing.... The one I got has had the 10 wired cable for AGA/scandoubler cut of :-(  I was thinking of getting me a female 15 pin VGA connector, but does anyone know how the 10 pins should be connected? Or should I get myself a male 15 pin VGA connector instead?

With female it would be like AGA out --> cable --> BMON

With male it would be like AGA --> BMON in case the AGA cable is long enough....

Any thoughts on what would be the best thing to do?

Use a multimeter. When unpowered, the AGA input is directed to the output of the BMon, and you can use the continuity (beeping) function of the multimeter to map the pins of the 10-pin IDC input to the 15-pin HDsub output. IIRC only 8 of the input pins are actually used; Red, Green, Blue, H-Sync, V-Sync, and two or three grounds.

Thanks, I will see if I can find a multimeter in a shop around here.
