Hi,

You have caught me a little off guard, as I do not have my tape cheater 
chart with me.  Assuming that the 2660 was the rack mounted high-end tape 
drive announced when the AS/400 was announced, it is bigger.  It is 
one-half of a rack height, and IBM only "officially" sanctioned it in the 
top half of a 9309 model 2 rack.

BTW, talk about tape drives that sucked.  This drive had less performance 
that the 3422 that it replaced on the System/38.  The 3422 was not 
initially announced on the AS/400, because there was a secret strategy at 
IBM to replace reel-to-reel with 8-mm, which, of course, failed badly You 
will notice that internal 8-mm drives are no longer available on the system.

Ultimately, several actions were taken in parallel:

Bus and tag support was made available on the AS/400, so that 3422 could be 
moved.  However if you analyzed the electric bills, you would realize that 
3422s consumed more power than Three Mile Island could ever generate, and 
they were cost efficient to replace.
Upgrades to the 2660 (I hope that number is correct - I am referring to the 
high end tape drive at the time of the AS/400s announcement in 1988) were 
made available, but from my imperical statistics, only 10% of those 
upgrades functioned properly.
The 3422 was IBM's fastest (reel-to-reel) tape drive to ever rewind, using 
more power than it taked to move the space shuttle (vertically from rest on 
earth).
IBM moved to move more advanced tape platforms to the AS/400.  The 3490's 
were first, followed by the enhanced (36 track) versions of this 
platform.  Later advancements like the 3570/3590 came out in the reverse order.
