Of course there are things that can be improved, and the Beogram 4000 certainly does have its weak points.
But making a Beogram better than the 4000-series of course includes ensuring that it still will be fully useable, connectable, compatible and of course also fully repairable 50 years into the future. - Just like its predecessor was (and still is!).
That'll be year 2070.
- At least.
Needless to say this rules out mask-programmed stuff, most digital content and generally all current interface technology, Bluetooth and the likes, none of which will be around in just 20-30 years from now. If that long.
It would be a shame to downgrade hundreds of Beogram 4000s to be that useless so soon.
In that case the least they can do is make the rebuild reversible.
Excited to see, what they can come up with.
