Subject: Re: Microvitec Monitor
I have looked at my microvitec monitor manual an it has all the connectors
used with various microvitec monitor the 7pin connector you refer to is a
standard IBM CGA monitor one with digital inputs.
Pin 1 Digital Red
Pin 2 Digital Green
Pin 3 Digital Blue
Pin 4 Intensity
Pin 5 GND
Pin 6 HSync
Pin 7 VSync
I will have to double check this but this should be right for the 7 pin din
plug.
It will work with a bbc as this uses a similar digital input interface. You
can either wire it up with nothing connected to the intensity or wire the
intensity to say +5v it does not really mater as the monitor has two
intensity levels per colour.
You probably need a sync splitter something like a "LM1881N Video Sync
Separator" or a "Elantec EL4581CN Video Sync Separator."
The same happens in the BBC monitor theres a board (module) which plugs into
the back of the monitor and this will control how the monitor acts. It
possible to remove this board and alter some jumpers on the monitor to place
it into analogue mode but I do not have the required PCB or service manual.
All I know is that this and 5 other monitor number are exactly the same ie
1571 1541, 1411 etc but with different plug in boards and they are covered
in the same circuit diagrams. Also there is a seris2 and seris3 version of
the diagram.

It's probably for a Philips 8833 monitor, which had a 7 pin DIN input.
