scsi cdrom upgrade on old macs to a scsi cdr/w? will it work?
« on: November 30, 2018, 12:44:13 AM »
hey just a quick question
i have an old mac that has a scsi cdROM but the cdROM is incredibly slow.. its like a 2x cdROM
if its a scsi cdROM, can i just replace it + swap it out with a 8x or higher cdrom? and have it work? ie: getting all the speed benefits of the faster drive including readin/writing (Burning) even if the original drive was not a R/W drive?

i would think if it works for my machine it would work for any and all old macs that have scsi optical drives...
but the machine im speaking of directly is a performa 5200CD (Road apple!) this would be one of the reasons why it was branded a roadapple lol
cdrom is so slow

it should work fine as a cd-rom but you might need to install third party drivers like toast or FWB or others to get CD-R/W functions to work, if at all.
G4/MDD 1.42 (9), G4/GB 500DP (X), Beige G3 400 (9), PBG4Ti 1Ghz (X), PBG3WS 300 (9)

got my mind on my scsi and my scsi on my mind

Should work just fine, tho you'll need Toast to burn with. I never needed the FBW CD toolkit for any of my internal SCSI CD burners.

Tho I had an old Powerbook 5300c with an external portable CDROM drive, that I needed the toolkit driver, unless I booted the system with a bootable Mac OS Install CD in the drive, then I could swap the CD with any other CD, and it would mount.

Little known fact, a bootable HFS CD has the Apple CD/DVD ROM driver in the partition table. Old World Mac's will boot from a unsupported HFS drive if you hold the right key combination at boot, or you have no other bootable disks.

As far as OS 9's builtin disk burning software, I don't think it can be hacked to work with SCSI drives. I was never able to hack OS X to burn disks from a SCSI drive, tho they will work for unsupported ATA drives with a small hack.

Likely, now that I know how to hack OS 9 Extensions, we could get Disc Burning to work in OS 9 on unsupported ATA drives, but that really doesn't help with SCSI, I just thought I'd put it out there for OS 9 users that want Apple Disc Burn software to work with replacement drives.
