When I last investigated the keyboard membrane position, we arranged for new ones to be made for the A500 and A600 machines. It was decided that it was not worth getting any made for the A1200 as AmigaKit still had new old stock keyboards for less than it would cost to make a membrane.
Have AmigaKit now run out of stock?
If so, how much interest would there be in getting membranes for the A1200?
I also need confirmation as to how many different A1200 keyboard membrane types there are (and are there different ones for Australia for example) - I believe they all use the same membrane, but who knows! Maybe people could list the part number they have by way of comparison.
