I've got a 1200 running OS4. What is needed to get this on the 'net? Can I use a PCMCIA to ethernet adaptor to connect to the modem? What software/drivers do I use?
Yes, a PCMCIA ethernet card is your best option, Aminet has the drivers for that. (3Com ethernet cards have good software support)
When you get the card just go to your OS4 folder and into the internet drawer, click on "Make new connection" and follow the screen props (go automatic, not manual and its dead simple)
