This graphics add-on unit was used on i386/i486 based single board computers from Siemens (or better Siemens Nixdorf Informationssysteme, SNI), I think.

Somebody has an idea what's the designation of the cable fitting on the top connector? Is it an VGA feature connector? What was the purpose of these adapters?
