2023-08-07 11:24:02 So, I think I'm going to do that "three instruction" bringup model on this little board. Just have the ability to run peek, poke, and "jump to" commands on arbitrary addresses. May as well call the peek and poke @ and !. Then I'll be able to poke whatever I want into ram and jump to it, and see how that works. 2023-08-07 11:31:42 I'll probably have to push the reset button a BUNCH of times, but sooner or later I'll get something I can jump to and come back from. :-) 2023-08-07 19:53:52 BTW, I modified the 32655 hello world program today and added a scanf(). It works in that direction too, so it won't be hard to get a little interactive "playground" going.
