Greetings,
Akira is correct. I've tried similar set-up. I'm using,TCP, was Miami and ALYNX(v?.?) from aminet. I bought his 56k modem the following month. hehe! :-P I've used my Friend's A500 with M-Tec(?) expansion SCSI 750mb HD, 8MB ram. ROM 2.05 ATT.
I tried Ibrowse2.2 but so many things are disabled like graphics, maps... It too worked fine.
See. Even on a min setup A500, you can get on-line with your A600. :-D
Regards,
Gizz
