I consider buying Lyra 3 A1200 adapter for connecting A2000/3000 keyboard to my A1200. I am aware of the solder jumper that must be closed for that purpose. However, it is not clear to me if the Lyra 3 package conatins the DIN connector or if I need to make my own DIN connection to Lyra 3 pins. If a custom connection is needed, can you please identify the pins location (clock, data, gnd, 5V)? Thank you.

Lyra 3 for A1200 has a mini-DIN connector, as it's primarily a PS2 keyboard adapter.
A2000 and A3000 keyboards use a standard 5-Pin DIN connector. You'll need an adapter from DIN to mini-DIN to connect the keyboard. These are available in PC stores and online.

Happy 2024 and thanks for the information. So the required adapter for Amiga 2000/3000 keyboard is DIN F (female) to PS2 M (male), right?
One more question (I guess the answer will be no, but I will try anyway) - is it possible to order Lyra 3 with the full jumper that would allow flexible switching between Amiga 2000/3000 keyboard pass mode and PC PS2 keyboard mode without any additional soldering? I am ready to pay extra fee for that

Correct.

That's not possible, as the mode is only checked during power-up of the Lyra3 controller. The pin is used as output during normal PS2 translation operation; it's a programmable output pin that can be used for switching power supplies on/off.

It is clear that changing the jumper state is possible only when the power is shut down. Nevertheless, I would like to keep the possibility to select between the two configs without hard soldering. At the moment I have an A2000 keyboard, but I might need to connect a PC keyboard in future, or swap between them from time to time.
If you have no capacity to do such "custom" modification of the hardware, I understand that, but I just wanted to make sure if that's possible or not. Thanks.

In theory, you can put a jumper there and remove that for a future change to a PS2 keyboard. However, the lever you'd be putting on the pads bears the risk of ripping them off just by trying to add/remove the jumper.
The amount of soldering you need to do is similar to adding such a jumper: Closing the jumper is not a permanent thing, but you can easily remove the connection by using solder wick.
