Merely, it is most likely due to market forces. If you are going to write a software package for sale, you will want to target it towards the largest possible market. Since there are more 8080/Z80's than 6502's in this world, new software tends to be written for these machines. This in turn causes more people to buy this type of CPU, which gives a still larger installed base, etc. While I happen to agree that the 6502 is a superior processor than the 8080 (and a Homebrew system I built uses it for that reason), I also own a Z80 system to make use of the installed base of software. In fact, if I ever write software for sale, it will most likely be for the 8080/CPM market for the reasons stated above. That does not change my opinion of the processor. Michael S.
