The Model B+ was essentially a stop-gap machine to bridge the gap between the Model B and the coming Master Series. While the B+ did certainly offer a few worthwhile improvements to the Model B's design it still had all the hallmarks of mutton dressed as lamb, including the cheap-looking stickers applied to dress up later 128K models. The market was apparently unimpressed as the B+ did not sell in the quantities of the earlier models.
