Hello,
Found few things not right in 8080/8085 implementation.
1. ANA/ANI instruction, HF flag was not set right because error in calculation of it (missing brackets)
2. 8080 have NF flag always set (it is not used flag but bit is always set)
3. On unused ports/not connected memory values from status word were readed not 00 or FF, that is why I add it as a new internal register, it can also be buffered by some external hardware, so this could help other implementations too.
Regards,
Miodrag Milanovic
