Hi

I aggree with Alfredo, there is no practical reason to analyse the "MOV A,ACC" behavior, since everybody can accept, that it was illegal.

If really the same useless behavior (wasting two bytes and one cycle) was wanted, "MOV ACC,A" can be used legal.


Hi Alfredo, to see, why the code 0xA5 was reserved, please look on the Intel 251 data sheet.
Also on most other architectures are one or more unused code reserved for future expansion.
