The SCSI card that I will eventually use is the ATTO SE IVD, but it si currently not installed. I'm pretty sure that both ProTools cards I have are the SA4 kind, but again, not installed. The RAM is maxed, and it worked fine in the WGS 8150 as well as in the Radius before I tried the G3 card. It also has a virtually brand new PRAM battery. When I start with extensions off or boot from Norton disk it says the processor is the 601 110 MHz, not the G3. I might try wiping the hard drive and doing a re-install of OS 9
