It is very possible to transfer files from a modern Windows PC to a vintage Mac using either a Floppy Emu or BlueSCSI (or other SCSI emulators). It is not nearly as easy as using a bridge system, but I do not have room for a bridge system so I use what I have. I download files from Macintosh Garden (or other sources), import them into an emulated machine, decompress the files there, save to a drive image, and copy the drive image to the SD card for the Floppy Emu or BlueSCSI. I use Mini vMac to put files onto my Floppy Emu, and Basilisk to put files onto my BlueSCSI. It definitely requires a few steps but gets the job done, but if you use Windows machines do not feel like you must buy another system to put files onto your SE.
