nope i dont think they can. However an Amiga and a Mac can both read PC formatted disks, which is good since Ive just got myself a PB1400. Well its on its way anyway..
right now im having a right hastle getting my emulated mac online, I belive TCP/IP is working correctly but I have no net apps on it to try it out and everything i add wont extract, keeps trying to open them as text files, very frustrating!
