Claude Sylvain’s and Jay Cotton’s asm8080 that is :-] Mad props for going old school with command line disassembler. Im too much of a GUI slave to attempt such a feat, I stick to ida/ghirda when disassembling PC bioses for fun (several uploaded on my github). There are just too many nice features like Type tooltips, automagic mechanisms and one click operations that would be tons of typing in text editor.
