Used CF card on a PCMCIA adapter
Now that I can run my Amiga CF in Winuae with a USB cardreader. I "cheat" and go online (just to download) using Aweb in Classic Workbench. OR I get Winuae to show my PC drives in workbench and copy stuff accross that way.
When I finish towerizing my main A1200 it will probably be networked in some way....
There's also CDRW....
