Join the Hunt For the Government's Oldest Computer (muckrock.com)

This is doubly true for computers and quadruply true for government computers. This lends itself to an obvious question: what's the government computer most in need of an upgrade? MuckRock has launched a new FOIA project to find out, and has already started receiving some interesting results.
A couple of years ago I heard of a late-70's VAX still being used at a small power plant. To my knowledge it controlled some sort of HVAC systems. Another old system, one I've actually seen, was a mid-80's computer of unknown make/model used to control traffic lights in a small city. It's funny, or actually impressive, to see such old systems still in use. The old-school guys that keep them running tell nice stories about flea market and eBay scavenging.

I've found that sometimes old systems leave footprints that last far beyond the computers themselves.
For example, a couple of years ago we had this working networked system that we wanted to upgrade one computer of. The issue was that the protocol used to talk between the systems was a custom network layer written on top of a serial protocol called DR-11W. The cards were rather hard to find, the hardware very finicky to get talking right, and finding good docs for our custom layer was a real challenge.
I eventually found out in researching it that DR-11W was in fact the serial printer port on the original PDP-11's back in the 70's. Neither machine was a PDP-11, but since every upgrade ever done was one computer at a time, we've had to maintain this PDP-11 printer port communications interface for the last 40 years. The protocol even required converting all floating-point values to IBM's old format even though neither side used that format! The conversion's not trivial either.
Our one vendor for these cards has since gone out of business. The story I heard is that they lost their building lease, and didn't feel like it was worth it to move. So it looks like next upgrade, the PDP-11 printer port networking may finally die.
The moral here is that just because the 40-year-old computer may be physically gone, it might not really be gone.
I used to run a pair hobbyist/enthusiast sites for fans of DEC's VAX and PDP-11 series of machines.
Shortly after 9/11, I got a phone call from someone at the Pentagon who was looking for certain parts so they could repair an older VAX that had been damaged in the attack. I was able to get them in touch with a third-party reseller who still had those bits in the back of a dusty warehouse.
It was surprising that they hadn't upgraded to Alpha (which had been out almost ten years) then; the telco where I worked had one big system that had gone through three company changes (DEC -> Compaq -> HP) and had been upgraded in-chassis from VAX to Alpha.
I think all large systems sold to the federal government are required to have service/support available for something like 5 to 10 years after final sale availability; can't find concrete details via Google.
Pro tip: *every* system is broken.
Every system should be planned for. If a Windows 2003 Server is still on the network at my job, a planned exemption is on file to postpone removal for 30 days or gets pulled off the network. The server owner has six months to migrate to 2008 or 2012, but some people insist on dragging their feet and waiting until they have no choice. The process is somewhat easier these days as all the servers are virtualized across a server farm.
