I would like to make a second question.
I have some programming experience, but, as I don't have any formal studies on computer science, y have many things to learn 8)
Perhaps any of you can recommend me some books on digital electronics, and specially, but not exclusively, some regarding 74xxxx logic chips
If they have examples to play with, I think it will be more didactic
Although I have read schematics, and bought books on 6502, Z80, and 68k processors, I need more background.
As you can see, nearly all my knowledge is self-taught, except for my past working experience as a programmer (not related to hardware)
Thanks for your attention,
