NASA Shuts Down Its Last Mainframe

I cut my eyeteeth on IBM mainframes and keypunching...

NASA has just powered down its last mainframe computer. Umm, everyone remembers what a mainframe computer is, right? Well, you certainly must recall working with punched cards, paper tape, and/or magnetic tape, correct? That does sound a little archaic. “But all things must change,” wrote Linda Cureton on the NASA CIO blog. “Today, they are the size of a refrigerator but in the old days, they were the size of Cape Cod.”


An IBM 704 mainframe from 1964.

The last mainframe being used by NASA, the IBM Z9 Mainframe, was being used at the Marshall Space Flight Center. Cureton described the mainframe as a “ big computer that is known for being reliable, highly available, secure, and powerful. They are best suited for applications that are more transaction oriented and require a lot of input/output – that is, writing or reading from data storage devices.”

The historical value would make them a great find for a museum or collector.

That last mainframe at NASA cannot be more than 6 1/2 years old.

Hell, where I work we just shutdown our last one. An S/390 made in 1991.

It's so much more quiet in the computer room without the tape drives, printer and network processor.

When I started here we were using 3 S/370s with two reel-to-reels. It was like having 3 VW vans parked in the computer room.

computer room. The noise comes from the 'open systems' side. Their disk storage device sounds like it's crushing rocks! They also have a problem with their multitude of 'servers' over heating the room temperature.

I just wish folks understood that mainframes still drive about 80% of all business in the world. The world's largest retailer has literally dozens of them.

was the air conditioning. A lot of them still had vacuum tubes here and there and they had to be kept cool.

They SUCK ELECTRICITY!!!! They're museum bait, not collector bait. Would you want to power up one of those? The fucking meter would spin off its spindle.

24/7 for a couple of years without a 'reboot'? Let me know when your laptop can process 52,000 Million Instructions per Second.

Now the desktop is another issue. It's on Win 7, i7 6-core at 3.33GHz with 24GB of RAM and about 9TB of disk space. MIPS isn't the only measure of power. People wondered why VisiCalc was faster on an Apple II (where it was developed) than on the first IBM PC. Think about it. A 1MHz 6502 has a minimum instruction time of 2 cycles and a maximum of 14 (averaging around 6 in reality). The 8088/8086 chips at 4.77MHz had a MINIMUM of 14 cycles and a maximum of 156 with an average of about 86. Literally apples to oranges.

Windows to Z/OS at the same time. It has up to 3TB of internal memory and just about unlimited disk space.

system and then went into RPG programming. Was hired by IBM in 1973 and went on to support mainframes for 30 years. Retired from them in 2003 and now work as a system programmer for my Z/OS systems.

Our class projects ran on an IBM 1620, in the middle of the night. Working on a card punch machine improved my typing accuracy, for sure. Mistakes took a long time to fix, since we just got our cards back the next day if the program didn't run properly. Uff da!
