I am hellbent on starting at the lowest level of computing.
Figure it's just easier to write programs to reenact that than
build a system on a breadboard.
1 write data to memory and regurgitate it?
That doesn't seem to be very useful by itself. Expensive pencil and sheet of paper.
2 Input data and perform an operation on it?
That makes more sense. Does add storage for a 'program' or 'set of instructions'.
Any thoughts on this?
