Commodore 16 and Plus/4

These computers are also called the '264 series' and they do have a common platform. Plus/4 is aimed to the serious user and it has 64K RAM and some programs built-in into ROM. The built-in programs are loaded with bugs so they are practically useless.
C16 was aimed as a replacement for VIC 20. However, people bought Commodore 64's instead so this machine did not become very popular. It lacks the built in programs of the Plus/4.
