The irony of it all is that I tried it when the fastest machine I had
was a PII 600mHz. It was faster than the "big iron" when MVS 3.8
was current. 

It's also amazing how far we have come since then. I was a big CMS fan,
but I completely forgot that you had flat "disks" (no subdirectories)
and you could only have 26 of them.

The disk drives one place I worked at had at the time were 3350's, which
had 2.5 gig per string of 8 (the picture below is six of them). They had
13 strings of 8 in one room (104 drives), almost the capacity of a large
iPod. :-)
