Tape Transfer Cartridge
This item is a Tape Transfer Cartridge removed from the Aurora in the early 2010s. This item is used as an operational program storage device. The TTC as it is often referred to, is in a pressurized metal box with either a red or green handle, each having slightly different purposes. Used by being inserted into the Digital Magnetic Tape Unit, the device functioned to provide software used within the aircraft computer system (GPDC). The TTC was programmed and prepared by AESOP and was an important development made in the 1980s in aircraft technology and computer advancements. The TTC was extremely reliable, simply needing a tape change periodically.
