I have an old Amiga 500 with an external floppy drive, it seems to still work OK.
I looked up Crossdos and I'm pretty sure my 500 is too old to have it, I only have a really early Workbench as well.
I don't even see anywhere in the back that I could put a null modem cable (I'm not sure where one would go, I only have a long serial and long parrallel port free there). Even if I did, would that allow me to transfer disk images so they are bootable, or just the data on them?
I'm not very good on technical stuff, so sorry for all the questions.
Failing that I could bundle them all up and chuck them in the post to you!
Edit: My God, I just came across some stuff I forgot I even did, like Virtua Washing Machine, Quiz Arcade (a Japanese style quiz game) and a really great City Hunter demo.
