Motorola 6800 family

The M6800 Microcomputer System (latter dubbed the Motorola 6800 family, M6800 family, or 68xx)^[1]^[2] was a series of 8-bit microprocessors and microcontrollers from Motorola that began with the 6800 CPU. The architecture also inspired the MOS Technology 6502, and that company started in the microprocessor business producing 6800 replacements.

The chips primarily competed against Intel's 8-bit family of chips (such as the 8080, or their relations, the Zilog Z80 range).
