From the keyboard:

Type PR#3 to turn on the 80-column card.
When the 80-column card is on, press ESC 4 to switch to 40-column mode,
or ESC 8 to switch to 80-column mode.
To turn off the 80-column card, press ESC CONTROL-Q.

From inside a program:

To turn on the 80-column card, use PRINT  CHR$ (4);"PR#3"
To switch to 40-column mode, PRINT  CHR$ (17)
To switch to 80-column mode, PRINT  CHR$ (18)
To turn off the 80-column card, PRINT CHR$  (21)
