I think that was the Apple II.
I should still have the C64's user manual tucked somewhere, but it didn't described the internal architecture. I recall there were a couple of examples in Basic to move sprites and to produce sound from the SID "poking" (the PEEK and POKE Basic instruction) values to a few registers.
- bitwize 8y agoISTR there was a complete programmer's guide available from Commodore, but it was a separate purchase.
- radicalbyte 8y agoIndeed, the programmer's reference guide was needed if you really wanted to understand the machine. The user manual had an introduction to basic as far as I can remember :) Some kind soul has scanned it: http://www.classiccmp.org/cini/pdf/Commodore/C64%20Programmer%27s%20Reference%20Guide.pdf http://www.classiccmp.org/cini/pdf/Commodore/C64%20Programme...
