More on this type of keyboard...
The IBM Instruments Computer System 9000 Keyboard (P/N 4780898) is a variant of the Model F/XT introduced in May 1982 for use with the titular IBM CS/9000 laboratory computer. It's mechanically identical to the IBM PC Keyboard but lacks flip-out riser feet, traded the square IBM badge for a rectangular one reading "IBM System 9000", and its cable now sprouts out from the left side of the keyboard instead of the back. Due to IBM's repositioning of the CS/9000 as a family of computers in 1984 (the CS/9000 proper was also renamed System 9001), this keyboard later became known as the Standard Keyboard due to the availability of the System 9002's Hybrid Keyboard.
