World's Oldest Working Computer On Display

an article today about the world's oldest working computer finally

a historical computer, over 50 years old, being put on display permanently." Seeing this makes me remember reading Cryptonomicon - of course, the definition of what's the oldest and working is up for grabs, but as a BA in History, it's cool to see stuff like this put on display for all to see.
I once heard a speech from a (now retired) academic who worked with CSIRAC. He said that the CSIRAC project was scrapped in 1964 because the British Foreign Office had a word with the authorities in Australia and sternly reminded them that Australia had no business doing research not related to mining or agriculture, and such projects belonged in the UK.
This is definitely cool... I hate to see any sort of technology go to waste. Hell... I have a Commodore 64 and a Commodore PET sitting downstairs.... at least I'll be able to tell my kids "See what WE had to put up with when we were 8 years old? REAL hackers don't need 4GB of RAM..." ;)
It doesn't work, it's just intact. There's actually an archival issue here. Do we keep CSIRAC "as it was", or do we restore it to working (and keep replacing valves as they burn out at the rate of at least one per day)?
When I was at the University of Melbourne, we were lucky enough to get a guided tour by one of the original members of the computational machinery laboratory. It's quite easy to see how the meme of the computer as ominous "electronic brain" took hold when you can literally walk through it.
CSIRAC not only had a hard disk (one platter, with a motor which delivered such low torque that you needed to put some pressure on the drive belt with a screwdriver to get it to spin up; I believe one of the engineers still has the screwdriver), but it also had a high level language, the interpreter for which fit in its (off the top of my head) 768 words of memory.
Oh, and another anecdote: When CSIRAC lived in The University of Melbourne, it was first housed next to the particle physics laboratory, which caused some scheduling problems, because CSIRAC wouldn't work when the cyclotron was firing. They also had difficulty with the mercury memory in hot weather, but I suspect all the early computers had that problem.

One thing I have always wondered about historical computing is the "what if" question. In this case, what if Babbage had got commercial success with his difference engine? I have wondered just how advanced a purely mechanical computer could be. What if the Victorians had thrown boundless cash at mechanical computers. Just how advanced could we reasonably hope these computers to be? I am most interested ;)

...electronic digital computer... Let's not be platform-biased.
Don't forget the work of Charles Babbage, such as his Difference Engine. I'm sure there were other computers before this one that still work (I think one of Babbage's still does).
