I'm having trouble with using a Lyra3 and an A2000. That said, I don't have an original Amiga keyboard, this was hopefully my only option for now. I get nothing out of the Lyra; tried it with two different keyboard adapters and finally two different keyboards (a mini ps/2 keyboard and then an IBM model M).
I see the keyboard light up, but that's it. Pressing left/shift-pause doesn't light up scroll lock to indicate config mode at all.
Since I had a ps/2 breakout board handy, I manually connected the clock/data signals to the CIA chip @ U300 to bypass the keyboard adapter, and still, I'm getting nothing. Did I get a dud, or could by motherboard be having issues? (5v is ok, and I tried swapping the CIA chips around).
