No it was not. It was binary comptaible i.e. intel code would run on the Z80. It was not a clone. It’s like saying AMD clone intel processors.

Definition of Zilog-80 given is : An 8-bit microprocessor from Zilog, a company founded by former Intel engineers. Z80 released by Zilog, and the basis for the computer boom in the early 1980s. A descendant of the Intel 8080, it was the favored processor in the days of the CP/M operating system. http://www.birds-eye.net/definition/acronym.cgi?what+is+z80=Zilog+80&id=1152269310

This example is very similar to J-7, which is a Chinese clone of Russia’s MiG-21 plane.

WHat I have metnioned MANY times is regardless of the encryption the instructions run on the CPU (IR) will need to be unencrypted. Encryption can stop you making sense of data in storage and/or across a bus but it MUST BE IN BINARY to be executed. By interfacing with the addressing you can unload a whole address unblock unencrypted. I have used this method myself on a stb by interfacing with a JTAG.

Well suppose that now you are given an Anupama based embedded system, whose access is encrypted in an unknown cipher (there are many unlike DES), so then will you be able to understand what the system does let alone cloning it ? Assume that you dont know Anupama’s architecture.

I asked you this coz in that Xbox hacking example that was given by you, most of the processors or chips that the author of the article hacked, were known to him. Even the Nintendo chip that was REd by ChipWorks must have been atleast familiar to them by studying previous kinds of nintendo cards (they could make out the separate circuitry for graphics, sound and other functions).

Why would a secret goverment porject involve IP and other legal restricions?

Well that sentence was from ChipWorks’ official website. Those were their own words not mine.
