Same, restoring a Macintosh SE FDHD atm that I bought from a traditional auction house.

Got it booting and the HD is filled with that previous owners CV and architectural drawings/letters for a long dead company in the Midlands (UK). The previous owner had died a few months before and his entire house contents were being auctioned.

I'll make an image of the HD and then replace it with something less ear-damaging... feels weird though.
