Support for faster modes is optional and negotiated over the bus in Asynchronous Narrow mode. As noted, most drives are not Apple "blessed" and will require a third-party formatter, such as Silverlining. I think you can get that from Macintosh Garden. Some of the oldest Macs can't access beyond the first gigabyte from their ROMs. The workaround is to make a 1GB System partition at the start of the drive, and one or more separate data partitions using the remaining space. - Jonathan Morton -- -- - You received this message because you are a member of the Vintage Macs group.

Re: 68Pin SCSI drives in a 68K Mac?
As this kind of happened to me a few years ago. I wouldn't mind asking a question myself. I bought one of the cheap 40 to 80 SCSI adapters, so I could use a 73gb (think that was the size, I know it's 70+GB). When I hooked it up my 8500, it didn't see it. I posted about it on 68kmla and the reply I got back. Was that some newer drives are not visible to the Mac, because they are based on a newer mode of SCSI, which the 8500 doesn't recognize.

Re: 68Pin SCSI drives in a 68K Mac?
Just realized, what I was writing was actually mostly applicable to the SCA 80 pin drives. On a 68 pin drive, there is usually a provision for on-board termination on the hard drive itself, unless it is a fairly modern U2W or newer SCSI drive. Anyway, if there is on-board termination on the drive, just put the drive on a cheap adapter, make sure it's at one end of the SCSI chain, and enable the on-board termination on teh drive and you should be good. You only need a drive with distinct upper byte termination if you're going to try to put the drive in the middle of the SCSI chain. My apologies for any confusion. It's been years since folks have regularly needed SCSI advice, so I'm a little rusty. -- -- - You received this message because you are a member of the Vintage Macs group.

Another small wrinkle is that "wide" SCSI supports IDs 0-15, while "narrow" SCSI only has 0-7 (of which 7 is normally reserved for the controller). You'll need to make sure a "wide" drive is set to a low ID that the Mac can physically access. - Jonathan Morton -- -- - You received this message because you are a member of the Vintage Macs group.

However In order to do it right, you must get an adapter which includes a provision to terminate the upper data byte. If you do not, then the upper data byte on the drive connector will not be terminated and while this often does not cause problems, it is not correct SCSI configuration. SCSI voodoo does not happen because SCSI does not work when it should. SCSI voodoo happens because often SCSI still works, when it should not. Anyway, the $3 adapters don't have any provision on them for termination. The adapters with termination are typically closer to $20. This doesn't make much sense, because its just the addition of some resistor packs. If they can sell the cheaper adapters for $3, then terminated adapters shouldn't cost more than $10. We had a long discussion about this over on 68kmla.org some years ago. Some stuff became inaccessible after the latest forum update, and that discussion might be old enough to have been vulnerable, so I can't guarantee it's still accessible.
