this one it is (this works fine for me since I probably have the scripts blocked for marktplaats ;))
anyway, it's probably some drawing program in cartridge.
To be honest, I doubt that. The packaging looks too flat to contain a cartridge.
Have a look at the second image on that ad...
Notice the black bar on the bottom of each card? That looks like a magnetic strip to me.
Also notice how the image on each card is constructed out of the shapes listed in the row on top of the card (next to the 'GRAPHIC CARD' text).
<guess mode='rather wild'>
I think these cards belong to a drawing program rather than actually being a drawing program. The drawing program than probably came with a card reader for these cards....
</guess>
BTW, the first image shows the name 'YAMAHA' in the bottom right corner of the card. What drawing programs did Yamaha release?

I think "card" here is more like "postcard", not hardware.
Probably, using some Yamaha's program, you should recreate the image depicted on the card, using a set of basic elements (see the topmost part of each card).
