I just made several modifications to the instruction set. This would be the version 0.3, nicknamed the “BAZ80” or “biblically accurate” Z80. This is a tongue in cheek reference to many posts on 9GAG showing representations of angels as supposedly depicted in the bible.
I have made a simulator for it, but I also ported it to a Z80-ICE platform. This will allow the BAZ80 to run on my Z80 monsputer.
See description of the Z80-ICE here:
