So, I got my A IIGS today. It has 5.25, and 3.5 drives. I don't have any GS software yet, as I have to make an ADTPro cable. I used an ADTPro 5.25 floppy I have, to try to format the 3.5, and it won't even list it under volumes. I tried a PRODOS User Disk, and it also doesn't show up there. The drive will run, and the LED will light when I do a list volumes, but doesn't show up in the list. Is this drive not supported by the floppies I'm booting from, or is the drive bad. It is labeled 1 on the front, and I have it tied to the GS, with the 5.25 daisy chained off of it, the 5.25 being labeled 2. The 5.25 shows up as slot 6 disk 1, even though the 3.5 is in the chain, and it cycles when I do a volume list. It never shows up. On a lighter note, the GS had a 1 meg ram expansion already installed...Great!
