We have now arranged for some new A500 and A600 keyboard membranes to be manufactured.
The A500 membranes are already in stock - and we are inviting pre-orders for the blue and green A600 keyboard membranes to help fund production - see:

The manufacturer has worked to merge the A500 and A500+ Mitsumi membranes together, so that they fit those versions of the Amiga which have ONE membrane connector - but will suit both the standard keyboard and the one with the extra international / blank keys
