So I've picked up an SBC6120 kit now that my number finally came up on the waiting list Still need to get it assembled, but I'm starting to scheme up a little development project that I'm kinda hoping to have ready for the next VCFW However, OS/8 isn't like DOS where there's a million different introductions to programming for it just floating around on the Internet (or CP/M where it's so bare-bones that the actual official manual is a mere hundred-plus page paperback,) and while I could just sit down and poke through everything Bitsavers has in the way of documentation, I figure I might as well ask around and see if anyone can point me to a basic overview of how the environment is laid out from the programmer's point of view. Is it like bank-switched CP/M where the program mostly or entirely resides in its own little world except for a bit of dispatch code to transfer system calls to the OS residing in another bank? I did see some mention in some of the documentation of a couple pages in high memory (within fields 0-2, IIRC) that are reserved for the OS, but I'm not exactly clear on the details...
