## Code 2001 font

This is the zipped ttf font Code 2001. This is freeware, by James Kass. This font renders many of the SMP plane Unicode characters, like Old Persian Cuneiform and Ugaritic and Gothic. The official download site seems to have gone, so it is mirrored here. Thanks to James Kass for his work.

## FIDO

Fido is an applet-based processor simulation. Fido is a simple processor simulation, designed to show the way the fetch execute cycle happens. It also shows the use of typical registers and addressing modes. It is based on von Neumann architecture, so that both program instructions and data are held in memory. You can select and run the bult-in programs, or write your own. Fido! Fetch! Execute!
