I still rock a 2007 iMac for my iPod and CD collection. You can still run modernish Firefox using a port called Powerfox on Mac OS X 10.6. Put an SSD and appropriate OS in these old machines and you'll be shocked at how fast they are.

These computers are generally obsolete, although they're still useful for period-accurate single-purpose tasks.

Claude can SSH into these old machines to patch issues and write bespoke software. We should reconsider what obsolete means nowadays if agents can help us upcycle old hardware.
