Use ~10€ to connect modern mouse to MSX

After one day of using the scroll function in symbos I don't want without it! Especially when your are browsing files!

I also build the mouse adapter and had the problem that I had no output on my serial monitor.
Checked all wires and connections, but couldn't find any mistake.
Got down the stairs grabbed a beer and tried again, no luck.

Took me 3 beers to find out that on a default Arduino Installation the serial monitor is on 115200 baud.
Bringing this down to 9600 baud gave me the output I expected.

I don't want you all to get drunk, so I thought it is worth sharing.

Hi!

I've received today my arduino nano v3 and succeeded to compile the program. The only doubt now is where to connect the wires

PS2 CLK to D11
PS2 DATA to D10
PS2 GND to GND
PS2 +5 to VIN
MSX JoyStick 1 to D2
MSX JoyStick 1 to D2
MSX JoyStick 2 to D3
MSX JoyStick 3 to D4
MSX JoyStick 4 to D5
MSX JoyStick 5 not connected?
MSX JoyStick 6 to D6
MSX JoyStick 7 to D7
MSX JoyStick 8 to D8
MSX JoyStick 9 to GND, the same as PS2 GND

Is that correct?

Thanks for the information and work done!

Conversion completed successfully. Now I have an optical mouse for MSX (and a joystick somewhat special)
I have to look a little thinner and longer cable, but the performance is perfect.

Now I'm trying to run SymbOS...

Hmm... Newer thought about left handed people... Should I add possibility to swap left / right button for next release?
