My TI-99/4a still works fine! That machine is rapidly approaching 30 years old. Never had any other vintage machines die on me, though I've had some lost over the years, and I've bought some duds on ebay. But of my Commodore 64/128 and Amiga systems, I've never had a computer die. Some 1541s, yeah, but never a computer. I expect them to stay functional for quite a long time still.
