There is some info over the net regarding 'some i8080 bugs were fixed in i8080a', but the exact bugs and differences are not usually disclosed. So, what is the exact difference between i8080 and i8080a?

    Perhaps you want to quote the relevant portions of the answer here, as well as the original author, in case the link goes down? – Cody Gray - on strike May 07 '17 at 11:22
  • @Cody Gray: I prefer not to do that since the reference is a (long) discussion between persons that do not agree entirely. – EL Dendo May 07 '17 at 19:06

    @ELDendo In situations such as this I usually use lots of ellipsis ([...]) and insertions for context [insertion]. – wizzwizz4 May 07 '17 at 19:31
