Amstrad. Their CPC range sold well enough that they ended up buying most of Sinclair Research and releasing a few models of Spectrum variants based on Amstrad industrial design. One model post-purchase Spectrum even included the same kind of oddball 3 inch floppy drive that Amstrad had been using (another had a built in cassette player, similar to what the first Amstrad CPC had).
