Programming model
With a slighly higher integration and a single 5V power (using depletion mode load nMOS), the 8085 was a binary compatible follow up on the 8080, the successor to the original Intel 8008. The 8080 and 8085 used the same basic instruction set as the 8008 (developed by Computer Terminal Corporation) and they were source code compatible with their predecessor. However, the 8080 added several useful and handy 16-bit operations above the 8008 instruction set, while the 8085 added only a few relatively minor instructions above the 8080 set.
