The first one seems to be a memory Expansion card,
the second can not be a graphics card because of the missing Video ram...
 
The first one is a combined memory expansion with uo to 8MB, and parallel (LPT) and Serial (COM) interface.

For the second one it would REALLY by ehlpful to have a picture of the connectors and the back.
 
The first one is a memory expansion for PCs. It was manufactured by STB and it goes up to 1.5 MB. Has IO ports.

The RGB adapter is a bit odd. Only three pins are connected to the slot, one of them being GND.
Could be a very simple framebuffer...
 
The 2 outer connectors is ground and the other one is probably +12V.
I would guess some sort of CGA to RGB converter for monitors with separate connectors
You connect the 9 pin from your CGA card and the monitor to the BNC connectors
