General Information<\/b><\/p>\n<\/td>\n

The 6800 was Motorola’s first microprocessor. The 6800 was introduced to directly compete with Intel\u2019s 8080. Much of the design was based on Intel\u2019s 8008. The 6800 had a very similar architecture to the 8080 with some differences at the register level. For example, the 6800 had two accumulators while the 8080 had one. The 6800 a smaller number of general purpose registers, but had a index register for array access to memory. The 6800\u2019s instructions are more complex that the 8080. Depending on the application either processor could slightly faster than the other.\u00a0<\/span><\/td>\n<\/tr>\n
