Just to say one did it?
In today's world, the way to implement the same algorithm would be to
use disk files; MUCH faster. With a TERABYTE of screaming fast disk
storage available for a desktop machine for about 500 pounds (around
$750 US) the REASON for a multi-tape sort has gone away. (Unless, of
course, one finds spinning tape reels exciting in themselves...)
$750? You're getting ripped off.
Fine. I didn't check prices this week. Mea culpa, mea culpa, mea
Hell, I carry a terabyte around with me now when I

Firewire drive, and a 500GB-equipped D-Link NAS box.. hey, I got to
have my movies and mp3s with me, right?).
I don't know. For myself, I can usually get by with a subset of
them on my laptop. And, if the voices in my head ask for a specific
movie, I can take that along on DVD. I have a couple thousand DVDs, so
my motivation to pack hard drives with video is minimal. Your mileage
(ahem, 'kilometerage' may vary.)
As to WHY you'd want to do a sort onto tape, my

Oh, crap. Classic COMPUTERS? Where's the Judy Garland Fan Blog?
It sounds like a fun project for somebody who as an

Heck, it might even make a fun programming project to
"emulate" it using a bitty box and some virtual "tape
drives". Lastly, it would make a great academic project
All valid reasons to be interested, I'll grant you. Perhaps you
will grant ME that these various reasons require somewhat different
types of assistance, or at least a different tone of enthusiastic
grunting, if that is all that is required. A screwdriver to adjust head
azimuth is pointless if one simply wishes to emulate tapes on disk, eh?

My 2 cents. Unfortunately, it's in Canadian coin.
Ah, that would explain it.
