As Always you guys are helpful. I was eyeballing a couple of HP drives on Ebay and picked one of those up this morning. That list helped in the research. I needed a Mac bootable CDRW and the speed wasn't the most important machine. It's a bit slower than my IDE Plexwriter however, I'll be ablo replace the SCSI drive and have CDRW and that's worth more than taking up two places on this particular machine! Thanks. SCSI is rare and expensive compared to its IDE cousins however, it appears that SCSI seems a bit more reliable too. On these legacy machines, my 52x doesn't burn as fast as my SCSI stock 24x Mac drive either when ripping CD's. I imagine that its due to the PCI Tempo Trio card I'm using and its interface versus the SCSI bus on the MOBO.
