HP 9125S Disc Drive

The 9125S was a single drive, modular 5.25-inch floppy disc system. It was designed for use with HP 150 Touchscreen to enable transfer of data from Touchscreens to IBM PC systems. The 9125S came with an HP-IB interface. The 9125S used the SS/80 command set. Oddly, the 9125S had almost the same part number as the 9125A pen plotter made for the 9100 calculator in 1968. The 9125S was replaced in 1986 by the 9127A.
