Summary
| Description | Instruction set for the MOS Technology 6502 microprocessor. The Rotate Right (ROR) instruction did not work the first run of chips. The solution was to omit the instruction from the datasheet and only list 55 instructions. The problem was fixed and the later chips had 56 instructions. |
