|Processor:||MOS 7501/8501 @ 0.885/1.76 MHz|
|Memory:||16 KByte, upgradeable to 64 KByte|
|Info:||Part of the Commodore-264 series|
The Commodore 16 (also known as: C16) is a Commodore home computer, which could be seen as the successor of the VIC-20. It was produced in the years 1984 to 1985. The C16, C116 and Plus/4 are part of the Commodore-264 series. The selling price was usually 99 US$. The case looks like that of the C64, but colored in black. More than 1,266,000 pieces of the C16 have been produced worldwide. In Argentina, the computer company Drean produced the C16 under Commodore license, as the company Sigma did in Mexico.
The OS environment is an advanced version of BASIC (version 3.5). The software is not compatible with the C64. The devices datasette 1531, joysticks and the diskdrive 1551 can only be connected (without adapters) to the Commodore-264 series.

Deviations of color table and control characters
The commodore colour table deviates at the TED after the 9th color (brown):
Color | Key com- | Color value | In program: | Or by PRINT "control character" | bination | for POKE | PRINT CHR$(X) | (in quotes!) yellow-green| <C=>+<3> | 090 | 150 | inverse graphic-X pink | <C=>+<4> | 107 | 152 | inverse ring blue-green | <C=>+<5> | 092 | 151 | inverse clubs light blue | <C=>+<6> | 109 | 153 | inv. vline right dark blue | <C=>+<7> | 046 | 154 | inverse check light green | <C=>+<8> | 095 | 155 | inverse clubs
Hint: There are some new control characters on the C16:
PRINTCHR$(027) escape key PRINTCHR$(130) text flashing on PRINTCHR$(131) text flashing off PRINTCHR$(140) help key
The C16 function keys are normally:
- DIRECTORY+CHR$(13) (the key is hit)
- SCNCLR+CHR$(13) +
- DSAVE+CHR$(34) +
- RUN+CHR$(13) +
- LIST+CHR$(13) +
- HELP+CHR$(13) or
An overview or modification of the function key binding can be achieved through the BASIC command KEY, either in direct mode or in programs. After a reset or a reboot the normally function key configuration is reset.
