The 35 year old interdata model 70 (oldest still-operating computer in Australia, we believe (EDIT: decomissioned late 2008, unplugged and carted away to the Sydney Powerhouse museum early 2009). Can anyone prove us wrong?). The 2MB disk pack sits out of the cabinet otherwise it fails, and we don't have too many spares left. I'm looking forward to this being decomissioned (ie, I have some hope of understanding the new system), but I certainly will miss the drone of 10,000 fans.
The adhoc chassis on the far end was the interdata's shared memory->10mbit ethernet interface. It had been there for over a decade. I do remember walking past it one night, and the whole computer crashed, so the entire observing stack needed a reboot.
