Say what you will about Commodore but they built some durable computers. I have an A1200 that I stored in a barn in 1992. In 2007, I decided to dig it out of the hay and see if it still worked. It fired right up and damn if it didn't have the correct date still stored in the clock. It was off by a few hours but I find it amazing that after 15 years it carried the correct date!
