Commodore C16
From Computer History Wiki
The Commodore C16, released in 1984 was probably intended to replace the Commodore VIC-20. The case resembled that of the VIC 20 or original Commodore 64 but was distinctive in that it was black with grey keys.
It had a 6502-compatible processor (MOS 7501 or 8501) and 16K of RAM. The C16 used Kernel and BASIC ROMs from the Plus/4 but did not include the integrated application software. It offered Commodore BASIC 3.5.
