This department also had a "tape picker". If a disk file "aged out", then it was transferred to a small piece of mag tape and place in some kind of pigeon hole. If later this file was accessed, the "tape picker" would have to restore the file to actual disk before you could use it. That could take between 2 and 5 minutes. Now I'm thinking that a little box of 5 or 6 multi-terrabyte disks could handle the whole thing with a minimum of fuss. Of course my time at the PPoE was 30 years ago. :-) My theory is: Things get easier and easier... until eventually those things are *not* worth doing anymore. -- numerist at aquaporin4 dot com
