If you are running GS/OS, both of Apple's SCSI cards will work with removable media in a nominal "hard drive". Under ProDOS-8, Apple's original SCSI card cannot handle removable media (it won't realise you've switched media unless you reboot), but the high-speed SCSI card will work. I used an Apple High-speed SCSI card with a SyQuest SQ-44 mechanism without problems (apart from the reliability of the SyQuest). Both cards also support CD-ROM drives (which have removable media by definition, but it isn't writable). You need revision C firmware in the case of the original Apple card. There might be different issues with a Floptical drive: if it appears as a custom SCSI device (rather than a "hard drive") then Apple's drivers won't access it (and this means it would be unusable under ProDOS-8). If it looks like a removable hard drive, then it should work for both 20 MB and 1.44 MB disks. You wouldn't get very far trying to partition a 1.44 MB floppy, but you could try. :-) -- David Empson dempson@actrix.gen.nz
