    en.wikipedia.org/wiki/MOS_Technology_6502

    The MOS Technology 6502 (typically pronounced "sixty-five-oh-two" or "six-five-oh-two") [3] is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology. The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of ...

    The original 6502 had several errata when initially launched. Early 1975 versions of the processor had no ROR (rotate right) instruction, even though they did have ROL (rotate left). This was a deliberate design choice by MOS Technology, as it was deemed that implementing ROR was too costly in chip area for the benefits it provided. [10]
