The CBM-II line sold poorly and ended up being extremely expensive to manufacture, as well as difficult to develop software for. Commodore did not release any sales figures or an official discontinuation date, however the B128/600 is the most common model in the lineup. Production ended at some point during 1984 and Commodore liquidated their remaining inventory in 1985. CBM-IIs were still being sold in Germany up to 1987. The exact number of CBM-IIs produced is unclear, however serial numbers indicate that at least 10,000 B128s were shipped along with a few dozen to a few thousand of the other models. It is believed that Commodore produced at least 5000–6000 of each machine.
