Mmmm, probably they're the same as the Gradiente Expert XP-800; so maybe a brazillian fellow can help with this...

They are different from inside, only the case and keyboard that look similar.

The CF-3000 is radically different from Gradiente Expert XP-800.
The CF-3000 can do Superimpose.

Hi, did you still have this manual?
I need the pinout of the keyboard in order to make an adapter for other external keyboard.
Thanks!

I have only one doubt, the connector has 20 pins only, but this pinout references pin 0~20 (21 pins). Maybe the last one (GND) is on shield?
Thanks!

I do not think it is necessary to connect GND to the shield.
