Hi Crispy I am knee-deep in setting it up (G4 & Ligic 4.04) . First you will need a Floppy -Disk image which is a down-load from the emagic site, for when you transfer it over. You will also need an iMate to give you ADB to USB capability. Depending on your set-up you may need a USB Hub but both the Hub & iMate are cheap. The iMate USB Driver is downloadable from Griffin technologu (also refered to on the emagic site). I will have much more info at the end of the day as I have hired a Mac/Logic "whiz-kid to fine tune it for me today (at least he'd better be for $A75 P/H!!). If you want to contact me directly, my email address is witsend@.... Especially if you have succesfully loaded Logic Clive Young
