I watched your video. So it can't be your A3000, since you have another keyboard that works fine.

I noticed in your video when you press certain single keys you get a bunch of characters. That look to me like hardware signaling/wiring. Your "A" key works. Other don't, etc

It must be related to something different about the A2000 Keyboard vs the A3000 keyboard you have.
I actually just bought a A2000 replacement Keycap (Left Shift Key) from a person who 100% confirms it was a A2000 Keyboard. But the Cap is totally different. The Stem on the other A2000 Keyboard works on Carbon type of contacts. My Amiga 2000 Keyboard works on Gold Metal Contacts that you can see right under the KEYCAP (so there are at least two different Amiga A2000 Keyboards out there).

On my A2000 Keyboard you can easily flip off he Keycap and look at the type of contact. Perhaps the A3000 keyboard isn't wired, or keymapped
the same, so you will have to find the keymap file to match it. I too am trying to figure out mapping (for my Bridgeboard since some keys don't map properly).


HOWEVER HERE is a (HANDY trick...Works on any keyboard any Operating system). I learned this just recently to at least get me typing when I really need to get a "\" which wouldn't type, so copying files in directories was impossible. (Works even if mapping is wrong).

HOLD the ALT KEY DOWN (Keep alt held down). Then punch in the (2-3 Digits of the ASCII code) that you want. (THEN LET GO OF ALT) .
The ASCII character for that ASCII code should show up.
Of course if the keyboard you have doesn't have "ALT" and "0-9" mapped properly, then this won't work. But if it does as least you know it's mapping.

Here is a handy ASCI table. http://www.asciitable.com/

Example. (HOLD-ALT) (065) (Let go ALT) should give you "A"
Example. (HOLD-ALT) (061) (Let go ALT) should give you "="

Not sure if you have Network/Internet on your Amiga, but you can also use a WEB based keyboard testing tool like http://www.keyboardtester.com/
--> I am looking for something like this as a standalone application for both Amiga and Amiga Bridgeboard PC (so if anyone knows of any, please passon)

This won't solve your problem instantly (and not the way you want to type :( ) , but gives you something to test and possibly type in commands to get a proper keyboard map loaded. Of course you could keep switching keyboards (changing keymap and trying again) to solve this (assuming you don't need to reboot each time)
