Does QIC-80 have twice as many Isn't the only difference between the Jumbo 250 and the Jumbo 120 that the 250 employs on-the-fly data compression algorithms (sorta like Stacker) to squeeze roughly twice as much data (on the average) onto the tape as the 120? Aren't the on-tape capacities and recording hardware the same? Just that software (firmware?) has squeezed the redundancy from the data presented to the 250? Are OS/2 drivers yet available for the Jumbos? _____________________________________________________________________________ Bob Davis, UofALA alum \\ INTERNET: sonny@trantor.harris-atd.com | _ _ | Harris Corporation, ESS \\ UUCP: ...!uunet!x102a!trantor!sonny |_| |_| | | Advanced Technology Dept.\\ AETHER: K4VNO |==============|_/\/\/\|_| PO Box 37, MS 16/1912 \\ VOICE: (407) 727-5886 | I SPEAK ONLY | |_| |_| | Melbourne, FL 32902 USA \\ FAX: (407) 729-3363 | FOR MYSELF. |_________|
