Sony Viewfinder 8-pin pinout?
 

Hello,
i want to enhance my XH-A1 with a tube B/W viewfinder.
With abut 500 lines, it should give more resolution than the custom LCD-displays.
I purchased an older viewfinder (DXF-M3A) and need to know the layout and function of the 8-pin connector interface in order to hook it to the composite out of the A1 and a 12V power supply. Looks like those connectors are still used in later models like the DSR-200 or the HDW730/50.
I only found information on the web about 10 - 14 pin connectors, so any information is welcomed!
All the best, Salar
