The Commodore 600 series was known as the B128 in the United States, and the machine that was known there as the B256, was called the 700 series in Europe. These machines are also known as "CBM II Low Profile" and "CBM II High Profile", respectively.
The 600 and the 700 series are almost identical, but 700 series machines have a built-in monitor, a separate keyboard, and a different character generator ROM. The 610/710 has 128kB RAM, the 620/720 has 256kB RAM, and the 630/730 has 256kB RAM and a co-processor card (Z80 and 8088 were planned, but it is not sure if these cards actually existed).
