Wico joysticks
« on: January 05, 2015, 03:34:59 PM »
So Ive got two Wico joysticks and I just got my A4000 up and running again. Both joysticks seem to be out of centre. When playing a game they both push the player to the right and no matter how hard I pull the joysticks to the left nothing changes or it will only stop the motion. Is there a trim adjustment somewhere that Im missing?

No but there are leaf switches inside you can bend slightly so that they are not mistakenly in the closed position when the stick is centred.

These are incredibly reliable sticks, though.  Are you sure there isn't something wrong with your joystick port?  Have you tried different sticks in the port, or the Wico sticks in another machine?

Ya, thats my concern that the port is faulty as they both exhibit the same behavior.
I wonder if its repairable.

I think i/o for these ports is controlled by a cheap, replaceable chip. So, yes I think. On Commodore's 8 bit machines this was the 6522 chip...not sure what the Amiga uses...maybe the same?  I hope it doesn't use the Paula!

The mouse works fine in port 1 so tonight Im going to try a joystick in that port on a 2 player game I know uses both ports to see what happens.

I don't know if that will tell you anything.  The mouse probably uses totally different pins on the port.

I think you've got a CIA chip issue.  Try the joysticks on another system (even an old Atari or C64, anything with the same connector), or try a known-good joystick on the same system.  But cross your fingers, maybe it's just the joysticks and a good cleaning and adjustment of their innards will do ya!

Im very sure the Wico's are fine as they have been kept in a storage location in my desk and they were working the last time I used them a couple years ago.
Is the CIA chip something that can be replaced or reseated?

Pretty sure they are SMD on most A4K motherboards.  A few people have had them replaced and had sockets added in the past.  You'll have to check your particular board.  On some models of A2K there's an inline fuse as I recall that can sometimes act up, not sure if this exists on the 4000's, as well, or not?

Also do the obvious - check for battery damage to any traces, bent pins inside the connector, loose solder joint at the connector, etc.

Battery was replaced a few years ago and there is no leakage or damage from the old one.
I guess one thing I can do when I get home is see if the problem happens if I have nothing connected to the port2, it should do nothing if I have it disconnected?

As noted above, the mouse and joystick ports are different, and without a custom driver cannot be used interchangeably; you can however use a multimeter to check both the joystick or the port.  Schematics are available online.

Is it possible a keyboard key is stuck that correlates to that joyport? just a shot in the dark but load up a game and disconnect the keyboard and see if you can go in all the directions.

Keyboard unplug has made no difference. I'm going to strip things down again and see if the ribbon cables going to the two ports are maybe loose or not seated correctly.

Well, after stripping down the Amiga to just the basics again looks like something is amiss with the Joysick/mouse ports as it still acts strange with both ports doing the same thing with both Wico joysticks. Im also getting strange cutting out of the video out to the monitor as it seems the Indivision is not seating properly but after removing and reseating the problem is still there.

Frustrating as I know I dont want to spend loads of money to fix this.

Did you take the Indvision out when you stripped the Amiga "down to the basics"?

You should see if you can replace/swap the CIA chips - that's an easy fix and cheap.  It might be the problem.  Unfortunately, you have the complication that the CIAs on the A4000 are probably soldered onto the motherboard, not socketed:

http://www.bboah.com/index.php?action=artikel&cat=51&id=2181&artlang=en
https://en.wikipedia.org/wiki/Amiga_custom_chips#CIA

I can't determine for sure if the CIA controls the directions of the joystick, or only the button - the information on the internet is conflicting and vague.
