Thought as much, I made my own cable, I've managed to unplug the beast, here is the connection layout:

The D (serial like) type plug that goes into the monitor is as follows;

``B G R x gnd
``| | | | |
__________
\ 5 4 3 2 1 /
`\ 9 8 7 6 /
``--------
```| | | |
```V H x x

Pin 1 = Ground
Pin 2 = not connected
Pin 3 = Red signal
Pin 4 = Green signal
Pin 5 = Blue signal
Pin 6 = not connected
Pin 7 = not connected
Pin 8 = Horizontal sync
Pin 9 = Vertical sync

(viewed from back of plug - wired side)


The 8 pin DIN plug, that plus into the back of the S-770 / 750:
``````B
``````|
G--[7] | [6]--R
V-[3] [8] [1]
```[5] ` [4]--H
`````[2]
gnd ---^
(veiwed from wired side, notch at top)

Pin 1 = not connected (+5V supply output?)
Pin 2 = Ground
Pin 3 = Vertical sync (TTL level
Pin 4 = Horizontal sync -ve polarity)
Pin 5 = not connected
Pin 6 = Red video output (TTL level
Pin 7 = Green video output +ve polarity)
Pin 8 = Blue video output


Now, heres a thing, the Roland manual has an appendix listing the connections, and it's wrong!
They have pin 3 open, and 5 as V sync.

Try and keep the cable run as short as possible, and don't forget to but on the covers for the plugs before you solder your connections!

Best of luck, and if you need additional information, feel free to ask.

Disclamer : any damage which may result of the above information is down to the user. As it works here!
