Re: 9347

Yep,

In the initial AS/400 announcement/shipment SORELY lacked any decent tape drive.
What I had heard was that IBM had contracted someone to do this and found out at
the last minute that these folks were stepping on their naughty bits (what's 
that
from ? <BG>) so IBM brought it back in house and was WAY late with anything. We
ended up getting a - gee forget the make, can't believe that ! - well anyway it
took 3480 catridges and could handle a 10 cartridge magazine !!! It was the 
size of
a LARGE refrigerator but SURE beat the 9347 we also had. Gee Al it is hard to
imagine ANYONE backing up with a 9347 in 1999 - no wonder they weren't doing it
<BG>... This 9347 is STILL in a 530 RISC machine because some of SSA's "alliance
product" (or whatever they were called) could ONLY supply stuff on 1/2" reel
tape... There is also a 3590 in this system too, by the way !
