I'm sorry to have experienced it....
At the same time, I also got a boxed copy of AppleWorks 5, which is also lost.
8.5 was the only Mac OS versions I bought new until Snow Leopard came out in 2009. At $39 (or was it $29?), it was a no brainer! (a bit off topic, but relevant: all prior versions were too expensive to justify because I was daily-driving some combination of Mac OS 9.x, 10.1.4, Windows 98 and 2000 until at least mid 2006 and Mac OS Tiger, Leopard and Windows XP from then to at least 2009 or 2010, and they all did everything I wanted. Keeping up with the latest in security was somewhat less important back then (being forced to keep updating like we do nowadays became a thing actually relatively recently, like 2016 or so, if I remember correctly, though it was starting as far back as 2011), so I could pull it off quite a bit easier than now (2000, XP, Vista and even relatively recent but unsupported versions of Mac OS X are starting to get kind of hard to use online, and even though one can technically connect to an Internet-facing network, doing much of anything Internet-related on 98, early Mac OS X and Mac OS 9.x and earlier is completely pointless without extreme measures).
TL;DR: computing used to be much more fun before the use of fancy security and highly complex encryption algorithms became mandatory for everything.
