I'm still interested in finding good *modern* tutorials for the 8- and 16-bit CPUs. 6502 has several good ones (https://skilldrick.github.io/easy6502/ is the go-to), but I haven't found any nice modern preferably-interactive tutorials for the Z80, 6809, or m68k. Any of you know of any? #retrocomputing #z80 #motorola6809

@mcmartin Back in the days these chips were common, tutorials were called "books" and we got them from the library and read them.

@mcmartin I suspect the 6502 has a lot of resources specifically from folks doing home-brew for the Famicom/NES? But since these chips were mostly used in general-purpose computers, the programming environment was *self-hosted*. The chips themselves are generally very simple, and most of the important info you need is how to interact specifically with the hardware in your system, and that's often provided as documentation along with the development tools that run on the system. For example, along with my TRS-80 Color Computer, I inherited a book "TRS-80 Color Computer Assembly Language Programming" which includes a guide to the 6809 CPU, ROM subroutines included with the computer, and how to work with input and output devices (keyboard, graphics, sound, etc) on the machine… along with instructions on using the EDTASM+ editor/assembler and ZBUG debugger.

@mcmartin this site is a bit of a find. Not the most aesthetically pleasing but great for cross platform assembly and includes all the usual suspects https://www.chibiakumas.com/z80/platform11.php#LessonP104

@mcmartin I still think the Programmed Introduction to MIPS Assembly holds up, and covers everything in such a way that prior programming knowledge isn't hard-required https://chortle.ccsu.edu/AssemblyTutorial/index.html

@mcmartin "Rodnay Zaks - Programming The Z80" is one of my go to books. It can be found easily online as a .PDF download.

@mcmartin Of course I had to check my bookshelf, and see, I have still some "tutorials" left! ;-)

@mcmartin Have you seen https://www.chibiakumas.com/ Lots of CPU’s covered, though the colour scheme is an acquired taste imho!

@mcmartin I wouldn't mind a somewhat minimal 68008 board to potch with.
