Commodore SD2IEC

When using a SD2IEC and a 1541 floppy drive together it is possible to have a device id conflict. The SD2IEC defaults to device#8. The 1541 floppy drive defaults to device#8 as well.

To change the device id on the SD2IEC, power on the C64 but not the 1541. Then open a connection to the SD2IEC

OPEN 15,8,15

Then send a command to change the device controller ID.

PRINT#15,”U0>”+CHR$(9)

The SD2IEC should now be using ID 9. To test, load the directory.

LOAD”$”,9

Now power on the 1541 floppy drive. It should startup and work as device#8 as normal.

LOAD”$”,8
