There is also this page:
http://basic.hopto.org/basic/g850v.php
Click on the "Comuniaciones" tab (I can’t insert a direct link). The text is in Spanish, but automatic translation woks fine.
There is no resistance in the diagram, but I don’t know if it is necessary, because I haven’t make a cable for the G850VS.

There are inexpensive soldering kits available on Amazon or Ebay, perfectly adequate for such a simple task.

There's a 10K ohm resistance in the diagram or are you talking about something else?

It’s in the page mentioned above (I’m sorry, but I can’t put a direct link).

If you can't solder, have you considered simply buying a cable? They're readily available in Japan.

Does anyone know the ROM calls for displaying graphics (pixels, lines etc)?

All the documentation I've found only has text to graphics.

Any pointers appreciated.
