Yes, that timeline error stuck out to me as well. Recently I found Solaris 2.1 physical media, and the date on it is 12/92. My goal is to get old GCC running on it, but first I have to get it running at all. My sun4m is a SparcStation 20, so will probably have to find a sun4c or SS10.
Note to anyone trying to image old Sun CD-ROMs: anything below Solaris 2.4 (?) is a CD-ROM with a partition table. If you dd out /dev/cdrom on Linux, you may get only the first partition, in ISO9660 format. You will be missing the small UFS boot partitions. There should be one small UFS partition for each supported arch.

Seems like using /dev/sr0 on Linux works.
