Will the keyboard work with a simple passive USB to PS/2 adapter? I’d like to use this with a PS/2 KVM switch with several pre-USB computers.

Here’s another product to convert the new Model F to use PS/2 with full PS/2 emulation of USB keyboards:

Aten CS82U

That way you will have ps/2 support for the new Model F Keyboard.

Hi! Here as a former Aten CS**U user (had the 4 port switch).

This product has laughably bad PS/2 support and regularly hangs keypresses when using USB -> PS/2 in DOS, Win98, and WinXP. When using the device for just PS/2 -> PS/2, it reduced my Dell Quiet Key to 0-key rollover in some cases, AKA, canceled key inputs. I have also updated the firmware to the latest and the condition of the outputs remains the same.

I opened a ticket with their support department about these issues a week ago and have yet to have any response whatsoever, not even an email confirmation of the ticket. I have also read of others who have been told that “the device is functioning as designed”.

So while you might be able to do the bare minimum text entry on PS/2 machines, you will experience multiple issues when doing anything even slightly out of the ordinary. Commander Keen, for example, was unplayable through this device.
