   Wrong!, the 8500c was the predecessor to the 8505 and it DOES perform
compression.  However it's a full height device and I believe that the 8505
is a half height device.  In either case I would want Lago to replace my drive with
a like drive, you certainly don't want two different type drives in your 
Datawheel especially as the previous poster points out when a non compression
drive tries to read a compressed tape.
