Even though the crew neglected to “park the disk” ~ amazing.

I don't know, I would hate to wake up in space one fine morning and see the "blue screen of death" looking at me

[Reaganesque]

Even the latest Windows version, I believe, runs on top of DOS. So, all PCs have DOS on them. Another reason to buy a Mac.

I was running some DOS research software in the lab just this pst week (seriously). Worst part about using DOS on an occasional basis is trying to remember all the commands. Otherwise, it works just fine.

The shuttle computers were programmed in the 70’s they have never been upgraded. The “additional” computing power comes from notebooks literally bolted to the airframes. The control computers are the same ones that the shuttles were designed with.

The computer was running DOS???????????? What year is this? Considering when a 340MB hard drive was state-of-the-art, I'd say the late 80s.

[ImJustAnotherOkie]

An esoteric piece of info, a 340mb drive will be broken down into 4K-8K chunksin DOS so the data could be recovered in large contiguous chunks.

What year was the shuttle built? Many military computers run old operating systems on old hardware. The Computer in the AWACs dates back to the mid '70s, but has been upgraded once since then, although it's still the same basic design. It's called the IBM 4PI, because architecturally, it's like two IBM 360s. The crews call it their "steam powered computer."
