The Commodore 16 (short for: C16) is a Commodore home computer, which was the follower of the VIC-20. It was produced in the years 1984-85. The C16, C116 and Plus/4 are part of the Commodore-264 series. The selling price was often 99 US$. The case looks likely the C64, but colored in black. The production of C16 worldwide are over 1.266.000. In Argentina produced the computer company Drean C16 under Commodore licence, however the company Sigma in Mexico.
The OS is a advanced version of BASIC (version 3.5). The software isn't compatible to the C64. The devices datasette VC-1531 and the diskdrive VC-1551 can be only connected (without adapters) to the Commodore-264 series.
