Hello guys, I have an Amiga CD 32 (Rev 3) with controlers input problems, Joystick & Mouse fire buttons work fine, but directions don´t (I managed to get a game going & It´s like it´s always pressing up, so it is blocking everything else) It isn´t the joystick & mouse problem because they work fine on a Amiga 500.
What i have done until now :
I have scoped U34 and realised that the directional joystick signal inputs from the controlers are arriving to pins 2,3,4,5 & 10,11,12,14 so all seems fine here.
Pin 16 VCC has +5v also , so it seems fine
Pin 15 (MLD) output signal that goes to Pin 21 on Lisa is showing a nice wave form on Osciloscope But PIN 13 (QH) that goes to MDAT on Pin 20 of Lisa is showing a strange noisy wave & the khz are all over the place
I am not an expert in working with the Osciloscope but that doesn´t seem right. The problem is that i already replaced U34 with a new one & the problem is still there.Atached are 2 photos from the signals coming out from Pin 13 & 15 if anyone can help me with this it would be much apreciated, I have this CD 32 setup with a CF Card with Paul Vince Amazing AGS instaled & i can´t play it, & it´s driving me nuts...
Thank you .
