Good luck with finding a replacement keyboard... but I think you'll have a difficult job getting one. The A1000's keyboard connector isn't used on any other Amiga (the A2000/A3000 use DIN plugs and the A4000 uses a PS/2-style plug).
I actually have an extra A1000 keyboard and cable that I was going to list on ebay! It is very clean and works 100%, pmail me if anyone wants to buy it!
