I think this nice card I got recently deserves its own topic 😉 Its a TSENG EVA/480 ET-2000 EGA card:
It has the same PCB as the NEC GB-1 COLOR GRAPHICS BOARD:

There a two add-on boards.
One connected to the feature connector providing TV-out. Dont know why the cable is soldered to the connector. As far as I remember it can also be connected via the feature connector without extra cable. Maybe to improve quality.
The other one...dont know yet, its not a memory expansion.
There is a Z80 and a HM6116 CMOS RAM on it.

The card seems to work without it.
And without boards:
Pictures in operation later...
