An interesting ebay find and what to do with scsi do-dads

I picked up an external scsi case with 5 devices in it. Two plextor cdroms, a zip 250 drive, and most interestingly a 3.5" floppy drive and some sort of memory card reader. This furthers my collection of internal and external almost-useless removable media devices. :-) It was sold as an IBM branded device, although I knew before hand that it wasn't. But there is an IBM sticker on the back of the case that says M/T 1609-F21 and a serial number. Not sure what's up with that. Maybe it's just an asset tag. So what could I attach this to? It has one centronics port on the back, so it must be terminated inside somewhere. I know the cdroms and zip drive would be recognized instantly by an amiga. I'm not sure what the floppy and memory card reader would look like. For example, supposing it's a 1.44mb floppy drive, what format would an amiga try to write to a drive like this? I would think that a disk format is OS dependent. I do have drivers to read fat partitions, so maybe it could read PC floppies. Or maybe since it's high density, it could read/write those 1.76mb amiga format high density floppies... or maybe not since it's scsi and the amiga specific floppy drives tend to be modified in an amiga-only way. I couldn't tell what kind of floppy drive is in there since I didn't completely take it apart, but from the back, it looks like a normal 3.5" floppy drive in a 5.25" scsi 50-pin adapter. Linux would probably autodetect and work with all of them. What would MacOS do? Also, the memory card reader has a slot for a type 1 or 2 pcmcia card. What could I put in this? A pcmcia flash memory drive seems obvious. What else? brian
