A2000 keyboard issue
My Amiga 2000 has been having a weird keyboard issue. Often after booting, the first key I press acts like it is held down so I get 200 or so of that char. Or, I'll click a key and a minute or two later it will register.

I figured it was just my original keyboard getting old, so I picked up the Lyra-3 PS2 adapter. It does the same thing.

When I took out my leaking battery, it had made a little mess on the mother board but it didn't look too bad. I notice the keyboard socket is right near there though; anyone see something like this?

That happened with a Cherry keyboard I used to have. Didn't happen with any other keyboards so I put it down to a faulty chip in the keyboard itself.

I think Cherry keyboards have a capacitor that goes old after twenty years.

There are also some fixes introduced in later A2000 board revisions to handle keyboard variations.

I was having a lot of issues including that one. I used contact cleaner on all areas and worked pretty well.
Worth a try.

Contact cleaner did the trick! It looks like some corrosion did sneak up on the socket housing so it might need to be replaced eventually.
