To autoboot .SCL disk images
On the Tools menu, click Options.
Click the Beta 128 Disk Interface tab.
If automatically load and run the first BASIC program in .SCL files is not enabled, click the checkbox and then click OK.
Note
When autoboot .SCL files is enabled, Spectaculator will automatically reset the Spectrum and begin loading from disk when a disk image is inserted.
Spectaculator will only do this if the disk is actually bootable and is inserted into drive A: (to avoid accidental resets).
To override the Autoboot feature, hold the Shift key down when opening a .SCL disk image.
