My belief is that these two CD-ROMs are among the most rare items in my collection. I have been unable to find any information about these CDs through official or unofficial means since I acquired them in 1999.
While unpacking and setting up a large shipment of iMac computers for a school district (iMac G3 266Mhz models in “fruit” colors), these CD-ROMs were left in the trays of two different iMac computers.
Presumably, these were the CDs used on the assembly line to make last-minute changes to the Mac OS before shipment. Also likely, these CDs were probably never meant to leave the factory.
One CD is marked C 1.5 Rework CD 1/04/99 Rev. 4007 born on date 1/25/99. The other is marked Elroy Video Touchup CD 5/13/99 Rev. 2010 born on date 06/11/99.
Incidentally, “Elroy” is one of the codenames used for the original iMac—a likely reference to the character Elroy, the son on the cartoon “The Jetsons.”
