Something that would give me a solid foundation for outputting a string, getting input, and outputting that input.
Sorry for the "newbie" questions. This is something I'm really interested in.
The
C64 Programmer's Reference Guide has a list of all the KERNAL routines that performs the I/O, in the "Basic to Machine Language" chapter. That level of stuff is a tad bit more complicated to set up, where the more simple Hello World style projects for assembly language tend to be things like making simple blinkenlights programs by changing single bytes that end up being visible.
While there are a bunch of people putting out tutorials and whatnot, I do still recommend the original manuals when learning to code for retro computers. They're pretty comprehensive and written to teach beginners to computing, and have plenty of type-in examples, while other contemporary books of the time get into exploring broader usage and concepts.
