I dont have much help to offer, but i will still welcome you to amiga.org.
There is 3 possibilities i know of though.. You could either use serial cable, get a network card, floppy disks or similar.
Also i want to give an offtopic tip.. and that is to open up your amiga and remove/or replace the battery as they tend to leak over time. The only purpose of this battery is to keep the clock/date on time while the amiga is off.
Good luck.
