Something like this ?
If you’re wanting a mirrored classic numpad with the bigger enter/plus I am surprised it seems like an unexplored niche of custom keyboard stuff. Can’t find any atm.
Could probably grab a numpad kit like this and mount the everything on the bottom of the PCB, but you’d need to do some soldering. On the other hand, that kind of kit is generally recommended as a first soldering project.
The US Navy has done this. It can be helpful to have a nuclear powered city/airport sail up and provide electricity and aid.
Not sure it justifies having 10 super carriers and several “regular” ones scattered about, but it’s good that they’ve done it.
