I finally got a cable that works with this type of plug. The attached file
shows the pin outs which I found by using a multimeter to see what the
connections are.

Cheers,

How to connect an 8 pin RGB monitor plug to a BBC RGB plug.
Both diagrams are shown looking at the plug from the inside.

The female plug on the back of the monitors looks like this:
 ______________
|_  4 3 2  1  _|
  | o o o  o |
  | 8 7 6  5 |
 _| o o o  o |_ 
|______________|

The male plug that goes into this socket looks similar except that it's just
a straight rectangle shape.
 ______________
|   8 7 6  5   |
|   o o o  o   |
|   4 3 2  1   |
|   o o o  o   |
|______________|

The female plug in the monitor actually has angled slots as well where I
have drawn the pins below. Up close it's more like this:
