With ALADCONV you can convert your old Aladin disks to Spectre format. The
program successfully converts 360K/720K Aladin disks to Spectre format
(whether they are MFS or HFS), while adjusting the disk size to 400K resp. 800K. ALADCONV automatically formats the Spectre disk; from TOS 1.2 and
upwards it uses the Twister method.
