That may be longer than reasonable... I'd use say writable CDrom
and if 9 years from now the ability to read that start getting scarce
I'd use the next technology that is current then and copy to that.
This would allow reading using available technology and also insure the
data was fresh. FYI: checksums and various other means can be used to
insure a file has not been compromized and also make recovery possible.

<> course). Or a Playtape player. Or an 8-track cartridge player. Music
<> formats do go out of production as well.

Some do some don't and a few are easy to make. a player for 78rpm disks
would be pretty trivial. Certain tape formats are fairly easy like
800/1600 bpi magtape.

It is necessary to look at the entire archival picture. copies of the
eproms/roms PALs are only a peice, spares to reproduce them and the
tools needed to insert code are also required.
