Non working joyport
« on: August 28, 2007, 12:04:07 PM »
I recently joined the A4000T club  :-D

But after trying some gaming on my A4000T I noticed the joyport is dead  :boohoo:  and I can't see any visual damage anywhere after stripping the computer down to the bare motherboard

Anyone have a clue what can be faulty?

Joystick ports not working can mean Paula custom chip failure.

How is the sound?

I have a feeling that joystick ports not working can also be an indicator of CIA failure but I am not 100% sure.

The sound is excellent

Might be high time to send this card to our french professor Jean Jacques Boulet

Have a talk to him, perhaps he can point you in the right direction without sending him anything?

Feels very annoying to have a dead joyport....my plans was to cut down my Amiga collection drastically and keeping just this  "A4000"

Will do  ;-)

First runners up for selling will probably be a CS MKII '040 + '060
A4000 motherboard...maybe two of them, a Micronik A4000 tower

I'm away from my home base this week, so I don't have my schematics handy. But I believe the joystick directional signals go through a multiplexer chip before going to Paula. That way, both joysticks can be read by the same 4 bits on Paula. If I recall, it's a 74LS157.

Isn't the PIV fast enough in MorphOS?  ;-)

Actually I'm quite impressed with how it performs; dragging windows is fast and even DoomAttack is fast (and that is with 68k emulation!). But I'd like to try some 3D stuff (in MOS and/or AOS).

I wonder though if PPC native PIV drivers for MOS would make it even faster.
