It is TS11 software compatible, and mechanically 1000 times simpler. It is a streaming tape drive, which means the logic makes up for the lack of mechanicals at the cost of speed. I have only been able to get it to stream once, but my normal use of tape drives does not require speeds in excess of the non-streaming 25ips. In general, special software would have to be written to make the thing hum at 100ips in streaming mode. I'm sure you will not need the speed unless you are going to duplicate tapes or go into the banking business. On anything less than a 780 it doesn't pay to get anything more expensive and on a 780 you can always enhance the tape pragrams/driver to keep the thing busy. No bugs found yet, but I have only had it for a month. P.S. I am using a UNIX* System V+ kernel with the standard TS11 driver.
