If you have the SA4 Protools Audio Card installed then yes, it will only connect to the 442 interface and not the 888. If you have the even older SoundTools audio card, then the only thing you can connect to it is the PRO analog, DAT, and standard Analog SoundTools interfaces. I've never tried and honestly since my 888's were and still are a bit pricey I'm not going to try that one. The 888's and 882's will hook up to a standard Digidesign SA8 (Elvis) Disk IO card, or the Bridge Card.

If you need the older Protools software that supports what you have, let me know. I have a cd made up for this type adventure.
