H-8487-A10 Open Reel Magnetic Tape Unit

The H-8487-A10 was a medium-speed open reel magnetic tape unit which kept the same performance as previous equipment, while greatly reducing size and weight (1/3 of the previous values), conserving energy (1/2 of the previous usage) and eliminating space used by the controller. This was achieved by miniaturizing the running system, using general-purpose processors in the magnetic tape unit (drive) and developing special-purpose LSI. The unit was first shipped in October 1980.
