    Yes, that's a great resource - nicest coverage of the basic architecture/instruction set I've yet found (though it doesn't cover the extended math instructions.) Though, again, lots on the architecture and not so much on the OS environment, but I suppose with a system where often enough things were just run on the bare metal that's hardly surprising.

    Now, though, having skimmed through the OS/8 Software Support Manual a bit, I'm both enlightened and a little more confused - it looks like there are system calls to open and close files, but not to read from or write to them!?

    (BTW, if anyone is interested in that XWindows panel-interface 8/e emulator he hosts a copy of, I got the source tweaked to build and run on modern Linux. What was with C programmers declaring absolutely everything untyped static in the '80s-'90s? This is like the third old program I've tried to build recently where the compiler chokes on that.)
