Matt did you mention the Revision your B2000 Motherboard is, I remember there being compatibility problems with Earlier B2000 revisions.

There's nothing connected to the joystick port, but lowlevel.library seems to think that the red button is being held down, as does stuff run through WHDLoad. Anyone have any ideas? I'm a little scared to plug in a CD32 pad (to see if the presence of an actual joystick without any buttons pressed would make a difference), just in case something gets zapped.

This machine used to be configured as a Toaster system. Could there have been a hardware modification for setting up a GPI trigger?

Thanks in advance!

pull and reseat paula chip. if thats not it try changing with a known good one. if that doesnt work check for a bad socket with internal break.

It's a 6.2, which I think is pretty safe.

You have checked the joy port pins ? If corroded the pins can sometimes catch and get pushed backward when inserting a joystick plug. looking at the arms on the back of the socket, where they enter the mother board, will tell you.

The pins all look good.

Ok, you'll all hate me for this being so simple, but not as much as I hate myself. Plugged in a CD32 controller. Now all is well.

This is - by far - the strangest Amiga problem and solution I have ever encountered. I hope I never deal with something like this again.

So, for the record, A2630 + lowlevel.library + no joypad = problem. Madness. Absolute madness.

I've noticed strange behavior from the lowlevel.library on a 3000 also. I installed this new lowlevel.library and it fixed all my problems:
