Cable for DB9 to Digitial RGBtoHDMI

This cable can be used to connect the following computers to an Digital RGBtoHDMI with a 16-pin input (which is not available at my own store yet):

PC with MDA graphics card

PC with CGA graphics card

PC with EGA graphics card

The 80-columns video output of the Commodore 128

Olivetti Prodest PC1

While it is intended to be connected to a 16-pin input socket, it can also be directly connected to the exposed contacts of a CPLD board (which is one half of the Analog RGBtoHDMI) as shown in the second product picture. But then it will no longer fit into my provided device case.
