Mostly just interested in 8085 optimized code for use with the standard ROM.
The thing I noticed was that they have gone beyond the 8080 and used 8085 specific instructions including the undocumented instructions. Which should be pretty efficient for handling register and stack relative variables. https://feilipu.me/2021/09/27/8085-software/ -- John.
