I believe IE was bundled starting with OS 8 or 9. (definitely 9, but might have started with 8) The document explains a lot of the 'gushing' Steve Jobs was doing about IE around that time. Sounds like there was at least a handshake agreement to push IE hard on Apple's side which they definitely did. (i.e. this goes beyond the previously published agreements re: bundling it etc as Steve in particular was really doing a hard sell on IE to Mac users at the time at a couple of events)
The document is also interesting as it helps explain why ClarisWorks died on the vine the way it did. I remember filing a bug report on a years old problem around that time for a family member which Apple never did fix, or anything else, in ClarisWorks until they eventually abandoned it completely years later. Too bad, it was a nice user-friendly, entry-level productivity suite.
