I have a friend who used to do major league play-by-play. Some games were dubbed onto large reel-to-reel tapes - the type able to handle a multi-hour game without changing tapes. He recently wanted these converted to a newer medium but finding anyone who could work with the old tapes was a more daunting challenge than I would have thought.
Even if you convert them to CDs, the CD technology (so I'm told) is already on its way out.
Yeah. Who has a tape machine capable of reading these 1" mag tapes? Last one I saw was 20 years ago. Most are in the landfill by now.
