Still waiting for the last parts to arrive (board, pin strip, on/off switches), but here's the layout draft already (see attachment).
This is true size. You'll note that the layout is quite narrow, but I deem it still feasible.
Don't want to have a large box on the desk - my goal was rather to have distinctive hardware buttons and switches with labels so I don't always have to scan manuals for the right key combo for what I'm just intending to do.
The pushbuttons are about half of the drawing's diameter in real life, the ones on the layout were made larger to give an idea of the space requirement inside the casing.
By far not all of the controls have been assigned yet.
I'll have to make my way through IL-2 1946 and IL-2 Great Battles keys and axis to finally consider the right layout.
Cheers!
Mike
