Ancient ATC computers

[Ranger One]

Entering the lions den indeed....

Hope one of you folks can help... one of my 'other' interests is preservation of ancient computers. I recently watched (well glanced at) a program, presented by that babe from the X-files as I recall, which concerned perceived problems with American ATC.

I sat up pretty rapidly when they started showing some footage of IBM 9020 systems (huge great things with flashing lights and switches, 1960s technology)... I'd presumed they had all been scrapped years ago, but no, apparently some were still in use up untill relatively recently.

So a question to any American ATCers out there: Do you know of any IBM 9020 systems that are still out there? Not necessarily still in service, but perhaps abandoned in warehouses, disused facilities, awaiting disposal, etc etc. Any leads on what became of these systems (date disposed, where they went) would be welcome. At least one of them should be in a museum!

Please pass the word, I'd really like to track one down. Email me if necessary at [email protected] - thanks!

The 9020s as central processors are all gone from operational sites since the early 1990s. they were canibalized for spares right to the last so doubt there is much left.

9020Es used as i/o processors were around a little longer, but are all gone now too.

There could be a few pieces, or whole machines, left at the disposal section at the FAA Aeronautical Center in Oklahoma City or at the Operational Support Service at FAA Technical Center in Atlantic City.

How come it is the ARTCCs that get all the ink? TRACONs aren't sexy, I guess. The ARTS started as a 256K core memory machine (and I mean core memory) and has been upgraded over the years. Processor was from a Navy design, programmed in a proprietary language. NO information security problems because it got no instructions over any phone lines and only a few people knew what the software looked like. Now days the hardware platform has been swapped out for a VME bus based architecture that fits in a small file cabinet size box. Same basic architecture is used for EARTS (Enroute ARTS). Now ATC systems use UNIX and other commercial off the shelf operating systems and are monitored, controlled and maintained remotely and everyone sweats how some kids in the basement of the science building (or worse) will hack in and cause goodness knows what havoc, so millions are spent on information security. What a racket.

We used 9020D here in the UK, until 1989, or thereabouts when the software was "rehosted"...I`m not sure where all the bits went. You are right about the flashing lights etc-- most impressive.

Aren't there loads going begging in Hampshire, somewhere near Fareham?

INCOMING!

From memory (a bit shaky) LOCUS16 at ScOATCC was so named for the massive 16K memory in each workstation...
