Thanks for sharing your wisdom everyone.
Ok - I have obtained an ADZ of a tools disk containing ASM-one, which I assume is legal since its freeware... I've unpacked it with gzip on the Linux box and now I have a file which I assume is an ADF. So where can I get a PCMCIA-CF adaptor for the A600? Do I need to hunt around on ebay or is it something I can buy new?
Thanks for your help,
Matthew
Buy EasyADF from Amigakit.com for 16€

edit: or buy an 44pin to CF adapter and use as harddrive, and a cf reader on you pc, then you can boot your enitre workbench in winUAE.
