All the Amiga hardware out there has lived well past it's design life...
That is the scary thing. I've an A500 pushing it's sixteenth birthday, another just turned thirteen and my two A1200's are ten years old. That's a combined age of Forty Nine years. From four Amigas!
Seriously though, despite all the busboards and accelerator cards that we update our systems with, the motherboard is always the oldest part. Not only that, but I'm reliant on floppy drives, power supplies, keyboards etc of similar vintage. Even my Mediator A1200 still has it's original floppy plugged in.
I'll just hang on a little longer, as it's not as if spares are in short supply in my house right now!
