via Slashdot, Programming Books, part 3: Programming the Commodore 64
Prologue about the book itself is worth reading, but the following really resonated for me:
Now I know that there is already plenty of old-fart nostalgia on this blog — a lot of people have interpreted Whatever happened to programming? as a yearning for the days when you had to do everything from first principles, which wasn’t really what I meant. But I do, I really do, miss the days when it was possible to understand the whole computer.
I’m not claiming that I ever had the level of mastery that people like West and Butterfield had. I was never really a big machine-code programmer, for one thing — I wrote routines to be called from BASIC, but no complete programs in 6502/6510. And I’ve never been a hardware hacker at more than the most trivial swap-the-video-cards level. But I did have a huge amount of Commodore 64 lore internalised. I knew which memory location always held the scan-code of the key that was pressed at that time; and where the screen memory-map began; and which locations to POKE to play different pitches on the various channels of sound, or to change the screen or border colours. I knew hundreds or thousands of those little bits of information, as well as being completely familiar with the horrible BASIC dialect that was in one of the ROMs. In short, I knew the machine in a way that I don’t even begin to hope to know any of my computers today; in a way that, I am guessing, no-one anywhere in the world knows their machines.
I miss that.
I know exactly what he means.
Long, nostalgic ramble after the break. Consider yourself warned.
