$15.00 BASIC Computer? Imagine a microcontroller that you can connect a serial terminal up to to get an ok prompt? What would happen if you changed one of the control registers can I see the effect straight away? Is it really possible to download programs onto this chip from the Internet and run them? Can I create a program and have it run at reset? Do I only need a serial link and two capacitors to get the ...
