Internal SCSI CDs were customarily SCSI ID3, the Mac/Boot Drive was ID0. Was there an Apple convention for internal SCSI Zip Drives?
6x00 SCSI Zip Drives - What SCSI ID did Apple assign them?

Agreed, typically Apple used SCSI ID 3 for internal CD ROM Drives.
I thought they'd switched to IDE Zips in the Beige Boxen?
Beige G3s came with both at various times for some reason.
Edit - duh me, because the IDE was screwed up on early Beige G3s. Two busses, but each would only take one device, so that's hard disk, and CD-ROM.
Later versions of the Beige G3 had better IDE that could work with two devices on one bus, so they might have switched over then.
THX!
MY External Zip Drives are well and truly buried. IIRC, they had a binary SCSI ID select switch? What were the 2 IDs?
edit: internal drives addressed almost the full range of available IDs on the Mac

SCSI Internal Configuration
Before mounting the device, you’ll need to configure it via the jumper switch located on the rear of the drive. SCSI ID setting: The three leftmost jumpers are used to configure the drive’s SCSI ID number. This can be assigned a value of 0 through 7. Usually, 7 is reserved for the SCSI host...
Tried that already, searched both pics and hits, futile waste of time as IDE and Internals muddy the mix. I've started asking general questions of the gang here. Thinking would be that whatever something doesn't pop up in on site search quickly, it's info to be circulated?
ISTR it was ID5 & ID6?

Please don't ask questions you can Google in less time.
Thanks much! Sorry, I'm half asleep and the ultimate point of my topic would be building a table of ID availability anyway. Mac only has 8 SCSI IDs available of the 16 in the spec.
SCSI ID 00 - Boot Drive - Unavailable
SCSI ID 01 -
SCSI ID 02-
SCSI ID 03 - Internal Opticals - Apple convention
SCSI ID 04 -
SCSI ID 05 - External Zip Drive - Conflicts with Apple Convention for Internal Zips
SCSI ID 06 - External Zip Drive
SCSI ID 07 - The Mac itself - Unavailable
Looks like I've got ID01 and ID02 available for a Zip inspired binary selector switch?
Can anyone thing of any conflicts with that pair?
SCSI ID 00 - Boot Drive - Unavailable

16 is only for later types of SCSI. It's 8 for SCSI 1 as was.
01 is usually second hard disk if fitted from factory and I'd call the first disk "primary disk" as there isn't anything saying you need to boot from that one specifically
ISTR UNIX workstations using all 16 IDs in the SCSI 1 era, no?
SCSI ID 00 - Primary Disk (Macintosh Boot Drive) - Unavailable
SCSI ID 01 - Second Disk: Factory installed HDD- Apple convention
SCSI ID 02-
SCSI ID 03 - Internal Opticals - Apple convention
SCSI ID 04 -
SCSI ID 05 - External Zip Drive - Conflicts with Apple Convention for Internal Zips
SCSI ID 06 - External Zip Drive
SCSI ID 07 - The Mac itself - Unavailable
OK, that'd be a 2/4 binary switch select choice then?

Then it probably wasn't narrow SCSI like the Mac was, had two busses, or was weird. Narrow SCSI is usually 8 IDs. Hence all the disks having 3 jumpers.
Yep my Beige is a Rev A. Doesn't even have IDE cabling for a second device on each bus.
