Die shot of Motorola 6800 [1]
The 6800 (M6800) was an 8-bit microprocessor designed and marketed by Motorola in 1974, with an architecture and orthogonal instruction set influenced by Digital Equipment Corporation PDP-11. Opposed to Intel's 8080 and MOS Technology 6502, the 6800 was a big-endian machine, concerning the byte-order of 16-bit words in memory.

Architecture
The 6800 had two accumulators and a 16-bit index register, stack- and instruction pointer. The direct addressing mode allowed fast access the first 256 bytes of memory.
