It was [[Original Equipment Manufacturer|OEMed]] from [[Storage Technology Corporation]]; the STC 3470 model. The TU70 supported 9-track operation at 800 bpi (using [[Non Return to Zero Inverted|NRZI]] encoding) or 1600 bpi (using [[Phase Encoding|PE]]).<br /> <br /> For use on the [[PDP-10]], it used a [[TX01 Magnetic Tape Controller]], which in turn was connected to a [[ DX10 Data Channel]], or a [[TX02 Magnetic Tape Controller]], which connected to a [[DX20 Programmed Device Adapter]].<br /> <br /> The tape transport utilized a single capstan, with air bearings, and two vacuum columns.<br /> <br /> {{semi-stub}}<br /> <br /> ==External links==<br /> <br /> * [http://www.bitsavers.org/pdf/dec/pdp10/KL10/EK-108OU-PD-002_KL10-Based_Physical_Description_Mar77.pdf decsystem10 KL10-Based Physical Description] - the TU70 is covered on pg.
