Best bet is to find some local HAM radio guys. Most of these guys are older, and into electronics. Chances are they'll know someone in town who has older, still-running hardware that you could use. They'll also know all of the tricks to reading old media.

I keep a stash of functioning old PCs in our storage room to read old data. All the way back to DOS 3.3 for me. The IT guy across the street has original IBM XTs that still are fully operational.
