Basic Computer Simulation

Directions: Step through the program already prewritten below (First "Burn Prom" and "Load RAM") . It will demonstrate how this programmers model of a simple computer works. Next, type in your own program ( starting at address zero) over the existing program. Burn Prom and then load RAM with data you wish to operate on.

New 2011: Free Circuit Kits that include circuit animations and simulation plus a PDF Lab manual.
Still Free! If you like this type of training, I recommend that you get my latest free e-book Electronic Concepts .

The key element of the Virtual Electronics Teaching system is our free e-book: Electronic Concepts. This e-book teaches electronics by explaining the operation of a variety of circuits. It covers basic networks, transistors, regulated power supplies and much more. Electronic Concepts is a hybrid e-book. Our hybrid e-books are meant to be read while viewing an Internet slideshow using our Internet Slide Show Control Matrix. Electronic Concepts can be downloaded from the Slide Show Control Matrix page in zipped PDF format. [ Go there! ]
