This one just arrived ... I need a better understanding of Z80 computers in order to be able to build emulators for the Danish made ones so they, together with their software, can be preserved for future enthusiasts and historians ☺️

Z80 is a nice assembly language, so should be fun to learn

I am going to be going into computer science, and I will probably be contributing my fair share of game preservation once I do.

Wow. I think I still somehow have my book on writing assembler code for a Sinclair ZX-81 computer (which, come to that, I also still have). 3.25 MHz FTW, baby!
