The subsequent 40-pin [[NMOS logic|NMOS]] [[Intel 8080]] expanded upon the 8008 registers and instruction set and implements a more efficient external bus interface (using the 22 additional pins). Despite a close architectural relationship, the 8080 was not made binary compatible with the 8008, so an 8008 program would not run on an 8080. However, as two different assembly syntaxes were used by Intel at the time, the 8080 could be used in an 8008 assembly-language backward-compatible fashion.

The [[Intel 8085]] is an electrically modernized version of the 8080 that uses [[Depletion-load NMOS logic|depletion-mode]] transistors and also added two new instructions.

The [[Intel 8086]], the original x86 processor, is a non-strict extension of the 8080, so it loosely resembles the original Datapoint 2200 design as well. Almost every Datapoint 2200 and 8008 instruction has an equivalent not only in the instruction set of the 8080, 8085, and [[Zilog Z80|Z80]], but also in the instruction set of modern [[x86]] processors (although the instruction encodings are different).
