The 1979 black Bell & Howell computer you see above is essentially a disguised Apple II Plus with slight modifications, that was produced by Apple for Bell & Howell in an attempt to breach the educational computer market. The micro was after all only sold to educational institutions, which Apple had up to this point failed to penetrate. As for the computer itself, it's quite the beauty, it's one of the rarest Apple II models and it's widely known both as the Black Apple II and as Darth Vader Apple.
You can bid on such a machine via this Bell & Howell Black Apple II auction, that includes the micro and two Bell & Howell/Apple disk drives. Just make sure you carefully read the description before bidding. Seller ships worldwide.
