You can also easily adapt an A500 keyboard although you would need a special housing for it.
A1000 keyboards are very rare, there are fewer keyboards than A1000s, cause back in the day Commodore gave big rebates on new A2000s in exchange for an A1000 keyboard. (I even have a keyboardless A1000 myself.)
Pinouts should be easy enough to find on the web, if not I can provide a few links.
