Hopefully someone remembers to stash a quartz coin reader, cable, etc etc...
There's an excellent example of how a digital archive can quickly run into problems.
Between 1984-86 the BBC Domesday Project engaged more than a million people from around Britain.
Children at more than 9,000 schools helped compile a statistical survey, personal thoughts and memories. The data was stored on special laserdiscs, then seen as a technology of the future.
Nearly two decades later, there were virtually no extant disc players able to read the specially formatted discs. After a lot of work, the data was made readable, but the case for digital archiving had suffered a setback.
