The cassette tape port is a .156" edge connector located on the back of the VIC-20, in between the user port and the serial bus.
This port is compatible with Commodore datasette cassette tape drives made for the PET series, the VIC-20, as well as the Commodore 64. It is sometimes used to supply power to devices attached to the serial bus such as the SD2IEC.
Pinout
| Pin | Connection | Use |
|---|---|---|
| A,1 | GND | |
| B,2 | +5V | |
| C,3 | VIA #1 CA2* | Cassette motor |
| D,4 | VIA #2 CA1 | Cassette read |
| E,5 | VIA #2 PB3 | Cassette write |
| F,6 | VIA #1 PA6 | Cassette switch |
- * The cassette motor line doesn't attach directly to the VIA. Rather, CA2 controls a higher-voltage source via a transistor. The Revision E schematic[A] lists this as "9V unregulated" with a 7.5v Zener Diode to ground.
