In regards to storage, if you can't afford a bigger SCSI drive, or a SCSI -> IDE adapter, I've found that one of the best things you can do is to set up another machine with an IDE drive as a server, either an LC630 or PowerPC Performa (both of which take IDE HDDs), or perhaps even a PC running Windows 2000 Server, with Services for Macintosh enabled. I have an old AMD K6/266 based PC with Win2K Advanced Server, and Services for Macintosh enabled. WIth 2 20GB IDE drives pulled out of old PCs I have almost 40GB of vintage Mac-accessible storage at my fingertips. In order to connect, you need I think AppleShare 3.7 installed, but apart from that, the PC shows up in the Chooser as if it were simply another Mac, and you can connect as if you would any Mac. SFM also has a way of preserving the Macintosh resource forks too, so long as you don't try and copy the files from within Windows itself.

Yeah, it takes a bit of mucking around, and you might not get it running the first time, but once you get it going, its definitely worth it, cheap scalable storage that you can access from any vintage Mac with ethernet, definitely a lot better than floppy disks, anyway
