Ahhhhhh. Thank you, Mr. Chasin. Assembly on the ATARI was awesome, and best of all it actually *sounded different* when you loaded it from your ATARI 410 Cassette Drive (It also required different instructions, since rather than loading data for the BASIC interpreter, you were swapping out the image itself -- mmap(2)ing directly into code from the disk, basically, hence no return to the BASIC prompt when you exited a program (meaning a reboot every time you wanted to run it, which quickly led to very small (i think i managed ~44 bytes by the time i was 10 or so) loaders+trappers). Ahhh, halcyon days of yore which modern programmers never knew!
