Your going to need a CDROM that can be set for 512 byte sectors. We use to use Plextor drives and if money was a factor, Pioneer. In the early days Plextor drives were quite a bit more expensive the all the others, and where usually faster.
BTW 512 bytes came from the sector size of a hard drive On Wed, Jun 15, 2016 at 11:47 AM, Swift Griggs <swiftgri...@gmail.com> wrote: > > On older Apple 68k machines, having an Apple-branded CDROM means you can > be assured it'll boot (though it's rumored that many generic SCSI CDROMs > work for booting) and also that it'll "just work" on most of the OSs. > > I'm guessing it's a simple check to see if the vendor in the firmware is > "APPLE".
