Whats a good CD-ROM driver for a SE/30 OS 7.0.1? It also needs to cooperate with a Jaz and Zip!
What I would suggest is that you first use the Apple CD-Rom Driver, and then use the iomega driver. The best place to start would be at Gamba: http://home.earthlink.net/~gamba2/index.html
... for the Jaz & Zip. Check some 7.5 & later installer disks, as it was included with the OS since around that time. For the CD driver, if it's an Apple-ROM'ed drive mechanism, the Apple driver ought to work. If not, I've had good success with the D2CD driver. Can't remember who produced it -- LaCie I think? -- but it should be available somewhere. I might still have an installer floppy kicking around somewhere.
Wasn't there also the Sunrise CD driver, that was free?
The Apple CD driver and Iomegaware seems to do the trick! The Sunrise did not work with the Iomega, but worked with out it.
