I learned to program in the 8 bit era, initially in BASIC on the TRS 80, then later assembly on the KIM-1 and then the 6809 based Dragon 32 (CoCo clone), which for the first time felt like a real computer. After that the BBC Micro and then the ARM, and eventually PCs.

Those first years were a real slog. I wanted to understand this stuff so much but it just did not click. I actually remember when it did, it was like a lightbulb going on and I went from 'this sucks, I can't hack it' to 'this is my future' overnight.

The I read a book by Niklaus Wirth and it opened my eyes to structured programming and various data structures (beyond variables and arrays). It's funny because even though I've read a mountain of books on computer programming by now that is still the one that gave me the most practical day-to-day knowledge which comes in handy every day.

Boy can I confirm that happening to find the right book back then was absolute key. And they were so expensive! Never really bought one.

These days it's almost painful to come across great books that would have been so awesome to have in like 1984.

Another series that really helped me was Leventhal's assembly language series. The problems in the books were relatively simple but they gave you a hold on one CPU if you already knew something about another and they served as instruction set reference as well (which were ridiculously hard to get here in Europe, and I don't mean those little cards but the full data sheets).

Between that and a book on parsing I managed to cobble together an assembler and an editor together with a friend.

Oh, and in the list of machines I forgot the ST, the first machine that I had with a megabyte of RAM.
