|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 the C16) was part of Commodore’s budget 264-series of home computers (including the C116 and Plus/4). Commodore sold the C16 from 1984 to 1985, intending it as the VIC-20’s successor, hence the budget price of just $99. In Argentina, the computer company Drean produced the C16 under license, as did Sigma in Mexico, and in total 1,266,000 C16s shipped worldwide.
The C16 resembles the C64 but colored black. It comes with an advanced version of BASIC (v3.5) onboard. This stops the C16 using the C64’s massive hardware and software base. The C16’s datasette 1531, joysticks, and disk drive 1551 connect only to the Commodore-264 series computers, though connectors are available for use with other Commodore equipment.
- Two joystick connectors (Joy1 and Joy2, round mini DIN, 8-pins, I) to connect a joystick

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.
