DB9 output on ZXUNO +

Mensaje por zx81zx81 » 03 Mar 2020, 22:05

Hi Folks,

I am trying to build my own DB9 output on ZXUNO+ to connect a Joystick and enjoy Atari 2600 core (since i didn't succeed to make it to work with the keyboard).

I was googling and looking here in this forum, but i was not able to find any hint or answer for the ZXUNO+.
There is an extension here https://www.antoniovillena.es/store/pro ... db9-addon/, but out of stock, that is using the extension connectors.

Código: Seleccionar todo

Ext1   [o] .... x17 [o]
        P01 .....   P17
 Ext2  [o] ... x16 [o]
 Ext3  [o] ... x16 [o]
I was able to find the pinout of the Ext1 connector using a multimeter :
Ext1 :
P01 - GND
P02 - Red
P03 - CSync
P04 - VSync
P05 - Bleu
P06 - Audio R
P07 - Audio L
P08 - Green

When i zoom the picture of the vgadb9-addon i am seeing connections between P09, P10 etc ... pins to the DB9 male connector.
So i suppose Up/Down/Left/Right/Fire signals are sitting somewhere around the P09 pins and next.

But, before to burn my ZXUNO+ i would like to know if someone has the official pinout of Ext1 ?

Any help would be appreciated :maestro:

Regards,

Zx

Hi

Here you have the eagle file for the edge expansion. So you can see where is mapped the joystick.
