Since Ben Eater has freed the inner workings of a CPU from the myth and made it accessible to the masses, there has been an incredible amount of projects in this area. 

But even before that, interested people have built their own CPU's, in hardware but also in software. Maarten Hus has a very special treat for us.

The virtual CPU called e-4917 actually comes from Prof. Richard Buckland and were part of his 2008 lectures at UNSW.

But Maarten has now put the thing in software, and brought the emulation piece by piece into the browser.

Caution: unfortunately unusable on mobile devices, but so well done, that you should definitely check it out on the desktop. Also for old 8-bit hares.
