I found this auction: http://cgi.ebay.com/MS-Word-98-SE-iMac-iBook-MAC-CD-processor-suite-/280...
This edition of Word 98 is very rare than the bundled Office 98. It was designed for iMac and iBook computers.
Also, I've found these auctions:
MacTest Pro for PPC February 1998 CD (We have the newer version)
MacTest Pro Disk Set v3.0 for PPC
Apple Service Source v2.5 (October 1997, we have the earlier version)
