6800

toc =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.

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. ||
