hi,
I link my amigas (2000, 3000 and 500) wit a laplink cable. Using am2ps as the transfer program (see aminet). Got for me the best result in connecting them. One can see each others drive, and just copy files to them.
I haven't used it on my a1200 yet, for that one I have a pcmcia network card laying around, but not tested it yet.
Jo
