The British company Acorn Computers picked their name to appear even earlier in the alphabet. Acer of Taiwan beat that, is there any company earlier than Acer?

There have been thousands of 'Aardvark Computers' around the world, but afaik they have all been support/service companies rather than manufacturers.
