AGFA Accuset 1200 with Star 600 rip HELP

hi, first of all I'm new to this forum and also fairly new to printing.
My line of business is clothing printing. (screen printing)

I've recently bought an accuset 1200 with star 600 rip.

i received no software with any of it, just ppd's on a floppy disc.

I need help on setting up to print from either a Macbook pro running OSX OR iMac G3 Running OS 8.

I have serial port cable into a transceiver the has a standard ethernet cable attached.

How do i go about sorting this?

ANY help is greatly appreciated !

thanks

jordan.
