It is an interesting card, but it is not worth the investment for what I need to do. It isn't hard to make Linux read the drive. I believe I can teach cpmtools about the formats I am using. I mainly use one standard one, and one I created for backups that does not have a system track. The disks are double sided, double density, 96tpi. The track layout is the same as a 720k 3-1/2" disk.
